Tank parameters first:
42-46 net gallons running ATS and top-off with non-saturated kalkwasser (1tbs/g).
Temp=79
Salinity=35
ph=8.35
Alk=7.5dkh
Ca=425
NO3=1
po4=0
Tests performed with RSP and Hanna colorimeters to duplicate results. I dose 2 drops of Zeobak twice a week and .5ml of Zeostart each morning. No other dosing and I even took the 2 part off line for now as the parameters are stable with just the kalkwasser in the top off. Running BRS Rox and PO4x4 in the same small reactor.
OK my build thread is here which gives a bit more info on the build. Right now I'm back to running the A350 - blue spectrum about 70% and white about 50% with the fixture mounted 10" above the water line. Had a Mitras over the tank for a few days running 14k @ 60%, ramping up and down. Light cycle is 10hrs/day with either fixture. Obviously the Kessil doesn't have the ability to ramp intensity. Two MP10s for water movement operating off of an Apex controller.
Now to my issue - brown corals. What steps would you take in order to get moving in the right direction? I know that po4 may not be zero, but it would be measurable if it were an issue. There is no algae growth in the display and only a slight haze on the glass after two to three days. As a matter of fact I don't think I've cleaned the glass in about five days and there's really no growth on the rocks. The ATS is working well, but not massive growth there either. The fish load is two small percula, one chromis and a small to medium kole tang. I feed two to three times a day - dried brine and flake.
How do I start to get color back in the corals? Never had this issue before on other tanks. Is it the lighting? Is the water too clean of organics? Do I need to dose another carbon source? What should be the first step so I can go through a process of elimination?
I went back to the Kessil because I was having issues with the GHL program and didn't want to mess with it any more until I get a better handle on what's happening in the tank.
Any and all help/suggestions are appreciated.
