I have a 46 gallon bowfront with a Fluval 405 filter. The filter is rated about 350 gph
. I only have about 5 fish, live rock, a few mushrooms, and hammer coral as of now. I was wondering which Hydor Koralia to go with. Two Koralia 1's rated at 400 each, or two Koralia 2's rated at 600 each. The ones will get me around 1150 gph
and the twos will get me 1550 gph
. Also I have 96 watts of pc
on the tank. What would y'all recommend for this setup?
