samo Posted May 22, 2012 Report Share Posted May 22, 2012 Hey guys, Looking at buying a fluval fx5 and most sites quote the flow rate at 3500l/h however the fluval site states the filtration cycle is 2400l/h. So my question is what's the difference and which number do I need to work off? Link to comment Share on other sites More sharing options...
brockssracer Posted May 22, 2012 Report Share Posted May 22, 2012 what I think it means is the pump is capable of 3500lph but once you add media and gravitational forces on the hoses it reduces to 2400lph. Link to comment Share on other sites More sharing options...
samo Posted May 22, 2012 Author Report Share Posted May 22, 2012 ah ok. So if I need 3000l/h flitration (8 x water volume) the one filter isn't going to do it? Link to comment Share on other sites More sharing options...
brockssracer Posted May 22, 2012 Report Share Posted May 22, 2012 if you added a 800-1500 lph internal filter that would add that little bit extra circulation Link to comment Share on other sites More sharing options...
samo Posted May 22, 2012 Author Report Share Posted May 22, 2012 I've got what will be a spare 1400l/h canister so I'll just throw that on as well Link to comment Share on other sites More sharing options...
brockssracer Posted May 22, 2012 Report Share Posted May 22, 2012 yeah, good thing about that is with 2 canisters you can stagger cleaning them so you always have one with a good bacterial load in there Link to comment Share on other sites More sharing options...
