Hello, I have been dabbling with reefing for almost 6 years. It is strange how addicting this hobby can be.

I have never been fully satisfied with my coral colors and growth. After about 2 years I moved my sump to the basement and created a refugium with DSB hoping to improve my water parameters. My test results have always read very good, almost undetectable Phosphates, 0 Nitrates but my coral colors are not where they should be.

I started using T5's and last year switched to LED's, of course right after I purchased the Radions they came out with a new model. It took long enough o take the wife into this purchase so I suppose it will take anther year or so to talk her into the upgrade.

I recently decided to attempt a ZEOvit system. I replaced my refugium with a ZEO reactor yesterday and I am hoping to see significant improvement with my coral colors and growth.

So, hopefully I will has something new to report in a few months.

55 gallon sump sectioned off, one chamber houses a ZEOVit reactor. Another 20 gallon tank housing a Reef Octopus 160 and a sperate 55 gallon used as a frag tank.

Using 2 Radion Gen 1, using the 20k setting on from 2 to 7, ramp up and down time starts at 10am and ends at 10pm.

I have about 300 gph flowing to my basement sump. My return pump can handle more however the drain gets rather loud if I increase the flow. I just added a Vortech MP40 for internal circulation.

I am debating if I should add an external overflow box to increase the flow through my sump. I would configure the drain to the sump with a full siphon and then leave my internal drain to handle the additional flow so I could keep the full siphon running correctly. I do have an Apex configured so if for some reason the tanks starts to over flow it will shut down my return pump...thus saving the living room wood floor.

I just started toe ZEOvit system. I have seen great results from others using this method and I am hoping I'll be able to replicate these results.

I'll let you know how it goes as I get into it further...........

Almost 3 months into ZEO now and I am still dosing the basics, ZEObac and ZEOstart. I think patents is the key, I don't want to start adding additional nutrients if my system isn't quit ULNS stable yet. I am hoping another week or two to start experimenting with additional ZEO products.

With my basement sump I was able to plumb it so my water changes consist of opening and closing a few values. A 5% water change takes about 2 minutes and I don't need to carry any buckets.

I have been running ZEOvit for almost 3 months and I am starting to see some improvements. Coral color is starting to come back, previously all corals were very pale and growth was almost non-existent.

Since the tank has been running for so long before starting ZEO i think it might take some time to get the parameters where they need to be. Right now I am working on lowering the Alk, since the coral growth has been slow the alk is not getting used up. my PO4 is also still a little high, .03 was last weeks reading, it has been dropping slowly.

Overall I am encouraged by the changes I am seeing.
