Is that the box hanging at the back of the tank?I was wondering....
The discus look fantastic and fat; looks great every time you post an update Zig!
Yeah there's a redsea 500 co2 reactor hanging bu the tubing above the heater on the back of the tank. It works great, but the suction cups suck... or dont suck, it keeps falling off the glass..
I love when people diary their tanks from start to present. It is looking good. Discus look heathy and happy. What temp/PH are you keeping the tank at?
Temp is 86F
ph is around 7.6ish.. I havent checked in some time..
