FAQ and Feedback

AquaticLog FAQ

The intention for this post is to help answer some of the questions you may have about AquaticLog. It will be continuously updated and will be pinned to the top. Feel free to leave your feedback in the comments below.

My name is Dmitry Tumanov and I had started AquaticLog as a website to help me get organized with my foray into reef aquariums in November 2012. Since then I had continued working on every year and have made over 740 updates to the website.

First versions of native mobile apps were written in 2014 and now mobile app is the predominant way that users access the service.

In early 2018 I’ve built industry first Artificial Intelligence recommender system that to this day helps making suggestion to aquarists on optimal parameters for their aquariums.

In late 2018 AquaticLog has hit 1,000,000 measurements mark, you can see real-time number of measurements taken so far at the bottom of every web page.

While I have my main job, both programming and reefing are my passions and I continue to work on native iPhone app, native Android app and website whenever I can. When you pay for the app you directly support this development, thank you.

Cloud Sync
AquaticLog app allows seamless syncing between iPhone, Android and web. Should you switch phones or even mobile platforms, all your data is safe. You can also make your data private or share with other aquarists to get advice or bragging rights.

Big thank you to long-term supporters of AquaticLog: EcoTech, AquaIllumination, NYOS, PolypLab and many others. You have helped a lot in expanding this service.

Free vs Pro
AquaticLog comes in two flavours - right of the bat you get your free account that gives you all of the features except for multiple aquariums and multiple photos. The reasoning is simple: all your photos are being backed up to the cloud and hosting it does cost money, plus if you have more than 1 aquarium it is more likely you'd be in the position where you could afford the service.

I've experimented with many payment options in the past: multiple tiers, locked features, but in the end I'm
trying to make it as simple as possible.

Having said that, please note that your financial support is very important for continuous improvement and growth of this service. Every time you renew your membership - it is a motivation for me to spend an extra hour on the weekend coding.

If you feel that I'm doing a great job and want to say an extra thank you, please consider sending a donation at

iOS 8.9 Released

AquaticLog 8.9 for iOS is now out, you should be able to read this blog post as well as any previous blog post right within the app. The app will also show you comments and gives you an ability to leave them (need to fix a keyboard issue).

Also fixed the bug that would cause the to crash when you click on your profile photo.

Focusing on Android for a bit now.

iOS 8.8 Released

AquaticLog for iPhone 8.8 is now out.

This release is primarily focused on bug fixes and I've disabled markets and messages temporarily as they were not getting enough traction.

Version 8.9 is already in the works and it features quite an overhaul to the way you can communicate with the owner of AquaticLog and provide your feedback.

Main focus for next batch of work is the Android app, I now want to take it to the same level as the iPhone. Once the two will reach parity, there will be a barrage of improvements that will hit both platforms.

Some changes are coming

Hey everyone,

As the solo developer of AquaticLog, I've been thinking a lot about it and where it is going. Summer is usually the time when I take a step back and look at all the features for iPhone, Android and web and decide what I will focus my time and effort on.

This time around I want to concentrate on the basics, a lot of extra features that I've added over the years are not used to the extent I envisioned them to, so I plan to pause on those and concentrate on the core functionality.

If there's a feature that is important to you or you wish you'd have - feel free to write to me and I'll make sure your voice is heard.

Have a great summer and happy reefing!

Aquarium Privacy

As you know, your AquaticLog aquarium data is all stored in the cloud. That means that if you upgrade your phone, switch from iPhone to Android or start using the web version of AquaticLog, you will have access to your data and your aquarium measurements.

Having data in the cloud is useful for sharing as well - you can simply send a link of your aquarium measurements to your friends when troubleshooting an aquarium issue and have another set of eyes review and find any parameter tendencies that may help finding the cause.

But sometimes you want your data to be accessible only by you. Many of you have asked for it and now you have this option. Available on the web, on iPhone and Android. You can mark individual aquariums as private and you will automatically be excluded from any searches or any web browsing.

Thank you for your continuing support. If you have more feedback - don't hesitate to write in.

iPhone and Android Updates

Tons of new features have been added to the apps.

In Android 6.7 you can now convert parameter units within the app: if you enter your Alkalinity in ppm, with a single click you can convert it to dKH. This feature is coming to iPhone in 8.7 (available to all beta testers later today).

You can now post items for sale within the website, check out "Market" menu option up top or within the iPhone app.

Tons of new improvements coming to both platforms soon, so stay tuned.

March 7, 2019

Android 6.6 is out

New version of Android app will bring you an ability to click on charts and bring up history for each individual parameter.

Just one step closer to getting Android - iPhone parity.

A few people had asked as to why Android feature set is trailing behind iPhone. The answer is simple - while I love Android, the vast majority of paying customers are using iPhone. And whoever pays will get a priority in the development queue.

This might disappoint Android users and some will suggest I find some other means of sponsoring development. To this I can say - the best possible way to support continuous development of both platforms is to pay a yearly fee. This is the justification for any further development and is the reason this platform is going strong in its 7th year.

AquaticLog iOS 8.2

Happy New Year!

We are kicking off 2019 with 2 new releases for iOS: 8.1 and 8.2. This features a great number of improvements and new features and bug fixes. It is now easier than ever to add multiple parameters for an aquarium at the same time, the chart view now lists all relevant parameters underneath.

The app is faster as well, making your parameter input speedy and efficient.

Here's to great 2019!

November 23, 2018

Import External Parameters

AquaticLog has offered an easy way to keep track of aquarium parameters on the phone and on the web for years. However, if you have an old Excel spreadsheet laying around or simply have a digital copy of your parameters, now you can easily add them to AquaticLog with one click.

Save your parameters in a text file, where every row is a measurement record (date timestamp and value) separated by comma. Go to the website, click on Log parameters and then on a parameter name you want to import. You will see the "Import" button which will take you to the import screen. One click to upload and you are done.

To everyone living in US - Happy Thanksgiving!

AquaticLog iOS 7.9

This new iOS release brings you revamped reminders: you can now specify for each reminder on whether to renew them at regular intervals or upon completion.

For example, you may wish to setup a reminder to check your top-off reservoir every Sunday, but your Alkalinity check would be every 7 days, so that if one day you do it a day earlier, it will remind you 7 days later.

You can also create one-time reminders that will not repeat upon completion.

As always, appreciate your iTunes reviews and ratings.

October 16, 2018

AquaticLog iOS 7.8

If you have more than one aquarium, you can now enter two aquarium measurements at the same time.

Say you have just measured Alkalinity in your two reef tanks. Simply click on the Purple Plus button next to either aquarium, then click on the Alkalinity label and you will be able to enter both values on the same screen.

More awesome changes to come.

October 10, 2018

AquaticLog iOS 7.7

This release has it all: you can pick your favourite parameters (click Edit after clicking the Purple Plus), this will also make those parameters shown as charts on the Measurements screen. You can re-order them as well.

Charts have been cleaned up and made more legible. You can click on each chart to see additional information about each parameter.

You can also set the upper/lower bounds for each individual parameter.

Version 7.8 is already in the works, if you want to participate - email us at

For anyone living in Canada - Happy Thanksgiving. And we've got a new feature for you: in-app reminders.

AquaticLog iOS 7.3 is Out

Phew, that's a big one. If you are reading this in your iPhone app, that means you are using the latest version - 7.3 of AquaticLog. A lot has changed since the last one.

You can now view monthly points - simply click on your points icon in the top right corner of the home screen.

Searching aquariums and users works great, you can follow individual aquariums and see their real-time parameters.

Settings - well, at this time there's a slight bug that will actually crash the app if you click on it, please wait until 7.3.1 will be released (a day or two) and you will be able to see the new Settings screen and manage your avatar photo in there.

There's a completely redesigned home screen now - it looks cleaner and you will see only one photo that might be of interest to you instead of many. If you pull down to refresh you will receive a different photo.

Finally, there's now "Feedback" button on the home screen. Use it if you want to communicate something directly to AquaticLog. Think of this as a Direct Message to Developer.

Happy reefing and thank you for using AquaticLog.

App Ratings

Now in its sixth year of existence, AquaticLog strives to be remain the best designed and most functional online and mobile service for aquarists all over the world.

Some of you may be surprised to find out that it is a one man operation and is not a full time job for its creator. Any work on the site is done in the evenings and weekends, taking away time from family and leisure. Yet it still continues and all three directions (web, iPhone and Android) are getting new features and improvements.

AquaticLog iPhone app is now at version 5.5 and looks better than ever: a large portion of the web functionality has been ported to iPhone, the interface is streamlined and beautiful. Lots of users are now participating in the beta testing. The app rating globally is at an abysmal 3.3 and that sends a message to the rest of the world and it is not a good one.

Android app has received a much needed update last year and is currently undergoing the same treatment as the iPhone. Its rating is 3.2.

It is your right as a user to feel frustrated when something does not work or when the app crashes. And when you give a Nike app a 1 star it sends a solid customer message to their headquarters. Indie development suffers greatly when judged the same.

Your annual financial support and app store ratings/reviews are what makes the app better every year. If you feel like making a difference, please go the App Store and leave a review. If you had left a negative review because something did not work, please revisit it to see if it's been fixed and email AquaticLog so that the feature can be addressed.

Thank you.

Live Photo

Here's a nifty new feature for you to use. You already were able to reference your real-time aquarium stats via AquaticLog Forum Signature feature. Now you can share an up-to-date photo of your aquarium on the web.

Head over to your aquarium photo page and click on the new "Live Photo" button.

This will take you to a webpage which is always the latest key photo of your aquarium (you can always choose which one to use, but by default it will be the last one you've uploaded). Copy that web URL and paste it to the program of choice. Here's this feature being used within Apex Fusion.

This is especially useful if you have multiple aquariums and don't have a live camera. Set this up on Apex Fusion and never confuse which aquarium is which. Every time you will upload a new photo on AquaticLog this image will automatically update.

iOS Early Access

Would you like to get an early access to the new iPhone releases?

AquaticLog iPhone app has been going through some rapid changes in the past few months. We have added a number of enticing new features: you can now keep track of your friend's aquariums, discover new incredible photos, the whole interface has been given a fresh coat of paint.

We are not stopping now, and if you want, you can review features as they are released by participating in our beta program. Simply email us at and request to apply. Not only you will have new functionality before anyone else, you can also provide feedback and influence the evolution of the app.

iOS App #3.5.6

As many of you had noticed, the AquaticLog iPhone app has received a lot of updates. It is now sporting a fresher look and a lot of changes under the hood that will result in a better user experience.

One of the features that was added is "Discover" page where you can keep an eye on the most interesting images that users upload to the website. More on that in another post.

We are just getting started with this round of changes, so there's a lot more to come. Keep an eye out for new features and let us know of any bugs that might sneak in.

Finally, if you have any feature that you'd like to see in the app - write in the comments below.

Website Update #570

Happy Friday everyone!

AquaticLog website has been updated (revision #570, yes there's been 570 software versions of this website to date). Fixed a few bugs and have added a few improvements, you can now:

- Move inhabitants between aquariums
- Rotate inhabitant photos
- Friends feed will now include videos and diary entries in addition to photos

Thank you for all your feedback.

Account Types

Historically AquaticLog has offered two types of accounts: a free basic account that gave users limited functionality on the site and a Pro account to unlock all of the features. iPhone and Android applications were always free.

While this had addressed the needs of the majority of the users, we have had a number of requests on both sides of the spectrum to either offer less functionality for a lesser dollar amount or allow users to access more advanced features and further hep the site financially.

We appreciate and cherish all of our users. And that is why we are introducing the following tier structure:

Free - this accounts allows users to log measurements via website or mobile app with some restrictions.

Basic - no restrictions when logging measurements and you get a few more options.

Pro - no restrictions, get up to five aquariums, upload many photos, Apex/ReefKeeper/Reef Angel integration, energy consumption integration, repeat activities, automatic water changes and automatic dosing. This list is always growing as we add more features.

Super - everything Pro has to offer and more (photo hosting, unlimited aquariums). Get this one if you work in the industry or you wish to go above and beyond in supporting this service.

Now the best news is that anyone who was a current Pro user in the past year is automatically grandfathered into a Super account. This is AquaticLog way of saying thank you.

Thank you for using the service. You can find out more about each account here.

Artificial Intelligence

This November AquaticLog will be turning 5 years old. The industry has seen a lot of positive changes in the way aquarists look after their reefs and there is now more knowledge and tools at their disposal.

One important aspect of reef keeping is to have a handle on water parameters. While some can be meticulous about every single parameter they can test for, others practice a much more lax approach and many are in between. No matter what your routine is like, you are guaranteed to keep keep an eye on your temperature, salinity and alkalinity if you want to be successful at keeping corals.

The combination of parameter ranges for a reef tank is as unique as your fingertips and may fluctuate daily. You can keep a low nutrient system such as Zeovit or can be completely off the charts for Nitrates and Phosphates and yet have a reef as amazing as Richard Ross' aquarium. Whether you are new to the hobby or are an old salt, you will target some parameter ranges.

We all know general guidelines and acceptable ranges, they are published in every book or forum article. You can try and mimic someone else's parameters. But what if there was a way to get suggestions on a specific set of parameter values that are unique to your aquarium?

Have you ever heard of Machine Learning? This Artificial Intelligence technology is what Amazon and Netflix would use to recommend you books and movies that are tailored to your taste. AquaticLog is the reef industry first to use Machine Learning to learn from 840,000+ measurements logged on the site and recommend a precise set of parameters that should take your reef to the state of equilibrium bliss.

The algorithm takes your current parameters (you can specify which parameters to use) and will recommend the adjustments or will confirm that they are in a good state. If you prefer to keep a high alkalinity system it will suggest different parameters then for a natural sea water aquarium. If you prefer to have low nitrates it will suggest a value for phosphates that is appropriate. If your system runs cooler than most it will find matching parameters as well.

This advanced algorithm would not be possible without heavy math, big data and thousands of successful aquariums logged using AquaticLog. We have been running this algorithm in beta for a few weeks and results have been eerily good.

We are excited to hear what your experience will be with this revolutionary new feature.

Keep on reefing.
