What kind of filter are you talking about?

Canister?

Wet/dry?

Sponge?

[koi]

Pond canister

[myjohnson]

Should be all good.

how big is the canister?

[koi]

Not sure but the max flow rate is said to be 2500 gph but the pump im planning to use is 4000gph

[cichlid1409]

on a canister i would think that would cause some bad pressure problems. since the output/input is not design to handle that much flow.

[koi]

Oh ok well its a pond canister just letting you know'

How does a regular tank caniser work? My friend is taking down his tank and giving me one

[jarrodaden]

Are you saying a cannister with a pump built in added in combination with a second pump?
or
Are you proposing a filter rated for 2,500 with a pump rated for 4,000?

I think you are proposing the second scenario. Keep in mind that a pump rated for 4,000 gph generally means that you can get 4,000 gph with no lift or static rise and no other restrictions. I sincerely doubt that you will get anything close to 4,000 once you added the various losses including a filter. Also, once you get any debris, etc in the filter the flow rate will continue to fall. It might work, but you haven't really given us enough information.

If you have both pieces of equipment, I can tell you an easy test to run to determine your actual flow in gph.

Will be getting canister filter (not sure how it works yet). Have 500 gph pump. Need/want pond pressurized filter rated for 2500 gph and want pump rated for 4000 gph
