Thanks for the replies so far. Let me try and provide additional info to see if we can figure this out.
The tank is 180 gallons, 72 x 24 x 24, the sump holds 70 gallons.
The return pump is Waveline DC 12000, around 3170 GPH, I know less with head so on.
Also have 4 hydor koralia 850, I think tank has ton of flow, maybe too much.
So the tank was going to be full high tech, but just did not turn out that way because of the plants I went with.
The light has total of 7 bulbs, 80 watts each, 60 inches long. The are all staggered, so I run 2 in the front and 2 in the back. If I pull anymore would it not cover part of the tank? I agree maybe too much light still and that the problem. I have one midday in the front and back, along with 1 aquaflora in the front and back
My drop checker always turns light green almost yellow, but not until it been on several hours. The CO2 is on it own pump which goes into the reactor, then back into the intake of the main return pump in the sump.
So are you saying turn on 2 hours before, and turn off at same time as lights? Should I increase the CO2 so drop checkers are yellow?
I will try post some pictures later today.
