Hi guys
I have a 125 reef in the living room / the overflows (3) go through thr floor and go into 2'' p.v.c / that takes the water over the dart room. There i have a 90 gallon refugium the p.v.c has a (Y) and a
ball valve feed to the fuge. there are two damsels in there lots of rubble rock and cheta morpha / and other macro algee / horse shoe crabs / snails / sea urchants / then the over flow goes out to the garage with the spill over from the 125 to a 180 gallon sump and all back up to the living room. about 1,300 gallons per hr. I had twin floresant lights on it / it just did not grow the macro to well just added a 150 coralife clip on for one side and small floresants on the other side. ** what shoud i add for light and or how long do i run these lights** sorry for the spelling and thank you for your help.
