Nice refugium setup, but it offers no info as to nitrate reduction without more info on test results.

do you keep the sump light on same time as the main tank? I want to do this to one of my tanks to keep the nitrates down. Did you notice a decrease in Nitrates when you started this up?

[bobbieward1234]

I try to keep the sump light on a lot, hoping that the java moss will grow faster. I do not check the nitrates, I just keep stuffing java moss into the sump from my planted aquarium with CO2.... Java moss is the best for this stuff

@bobbieward1234 hornwort absorbs nitrates faster if thats what your looking for and because it absorbs it faster it grows like a weed. thats just what i have read I do not really know from experience.

[bobbieward1234]

I did not even measure to be honest with you... I probably should

I made sure that the return line was elevated with a small piece of tube so that if the power went out it would not overflow. I did this my turning off the power on the pump and adjusted the return line accordingly until the water did not come close to overflowing in the refugium. I also kept the overflow box as high as possible to the surface so as soon as water was reduced the overflow box quit working
