I have had this aqualife t5ho for a couple months now and I haven't seen little to no growth in my tank. My tank has 2x 18w lighting 1x 10000k and 1x 420nm blue. Corals I have are mushrooms, Ricordia, Kenya tree, frogspawn, toadstool, candy cane, Monti cap, gsp, zoas, and Xenia. Tank has 14 gallon sump/fuge with 14 lbs of lr, a seaclone protein skimmer, and a phosban reactor.

Tank parameters:
Ammonia: 0
Nitrite:0
Nitrate: 5ppm
Phosphate: 1ppm
DKH: 9
PH: 8.3
Calcium: 250 ppm

Any help will be greatly appreciated.

Is this lighting adequate for my system? I ordered some kent calcium and some purple tech.

Should be fine lighting for a 10 gallon. A little strange to have a larger sump than tank. Sounds like you have a lot of critters in there that are using up the calcium and probably other nutrients quickly. I have used Purple Up in the past and still do once in a while to help keep my levels up and add Iodine into the system. My Xenia thrives on added iodine.

How long has the tank been up?

How should I lower the phosphates in my system? Will my phosban reactor help?

I've used pc lighting similar to the one 1mkwiet used. All the corals showed brighter coloration under these lights

Unless you have an algae problem, the 1 ppm phosphates is minimal and isn't an issue with why your corals are not growing as you would like. As far as growth, there might just be a limit to how much coral you can have and sustain growth in the size system you have. There comes a time when a sort of equilibrium is reached where there is not enough available nutrients to continue the growth.

Just a theory on my part, but something to think a:idea:bout.
