as for the chemistry those are the only test kits i have. its a 38 gallon (36x18x14i believe). As i listed above i am running HO t5s for about 9.5 hours a day at 234w. i am running a canister filter (eheim). In the filter there is carbon and puraphos. Could it be that it is time to change the carbon. It has only been in the filter for about 2 weeks? I also have a 2.5 gal fuge on the back. I am keeping corals along with some reef safe inhabitants. Its been up for about 10 months. I feed probably 3 times a week. I only feed frozen mysis, brine, krill and phyto.
