My First Saltwater Aquarium

Volume 46 Gallons
Dimensions 16'' x 36'' x 20''
Make National Geographic OASIS
Model Bow Front


This is my first Saltwater Aquarium. I have been building this tank very slowly. I purchased the tank on Black Friday in November 2015. Since then, I have been purchasing a few things at a time. These are the items I have on the tank thus far: Fluval 306 Filter, Hydro Protein Skimmer, 2 Hydor Koralia Nano 425 powerheads, Caribsea Ocean Direct Oolite (Live) Sand (2-3 bags), Aqueon Pro Submersible Heater 150 Watt, Marco Rocks, 3 Fake Corals. I started with Instant Ocean Salt, but I have upgraded to Red Sea Salt Mix. For bacteria starter I used StartSmart Complete, and I have always used Seachem Prime to make my water safe.

I do have an API Saltwater Test Kit and a Refractometer. I have recently purchased the digital salinity reader because I was not sure if I was reading the refractometer correctly.

I have read several books on Saltwater Aquarium keeping, and I continue to re-read them as I get closer to getting my first fish.

I have been running my tank with inhabitants for over a year. Things have been going well. I do have a problem with green hair algae.
