I wouldn't use the Rio PH
. The Remora should run this tank, and generally underskimming isn't a main source of algae.
How much skimmate/skum/crap is it producing?
55g reef, 2x250W 10k MH
+ 2x96W PC
actninc, 10g sump, AquaC Urchin skimmer, 65lbs LR
xenia, mushrooms, wels. open brain, fungia radiata (orange), green eyed zoos
flame angel, mated pair of false perc, 6-line, firefish
20gH electric yellow cichlid
