I currently have an fx5 on my 120 and will be upgrading to a 240 soon. It says it can handle 400 gallons but i hear of a lot of people using multiple big canisters on a tank of this size. Am i going to be getting enough filtration when i upgrade?
JK47;4988073; said:I do not think you will be pleased with one FX5 on a tank that size. My 300 gallon has the same footprint and a single FX5 would not fit the bill for long. Two is far better IMO, if nothing else for the mechanical power.
