well I know this is old but seems better then starting a new thread!
I got my 2nd FX5 but was thinking of getting another 2 (2 per tank) then I got an 2217 and was hoping to get some advice on using a fx5 with a 2217 will it be enough for a 150G Bio wise, The american tank is going to be heavly overstocked as many people say its the best way to keep some of the fish I am after.
Trying to get my fish room some what going this month so hoping to cut down on price can get 2x 2217 for 1x FX5 but not sure if it would be good for Bio on such a large tank.
On my 244 tank I only have 1 FX5 and its on a timer running for 30 minutes then off for 30 minutes just like a refrigerator which saves allot of electricity, wear and tear without affecting performance or beneficial bacteria one bit. I also have a sump which I feel is necessary on a tank larger than 100 gallon to help maintain water level, additional low cost filtration, boost beneficial bacterial better then a canister alone, increase water volume, serves a a breeder for Black Molly feeders which also keep all diterous off the sump bottom as molly waste turns to liquid not solid they actually keep the glass bottom sump tank spotless. 1 FX5 can easily handle 200 gallons, having 2 on 200 gallons is a bit of a waste like having twice the air conditioners needed on a house running non-stop without a thermostat IMO.;D
