I am looking to order some equiptment for my 90 gallon reef tank. First should I get 2 150 watt Visi-Therm heaters, or 2 200 watt heaters. They will be going in my 55 gallon sump.
Second powerheads. I only have 1 return on the tank that is 600ish. Koralias are on sale so should I get 2 K4 that are 1200 gph
and 1 K3 at 850 gph
. I would put the K4s at the ends of the tank and the K3 on the back glass. Or, would it be better to get 3 K3s?
Return + 2 K4 + 1 K3 = 42.7times turnover rate.
Return + 3 K3 = 35times turnover rate.
All help would be greatly appreciated.....
