koi filters on tropical tanks???

[IKeepPacu]

in my planning and search for filtration for my 1800g tank, i started looking at pond filters.

however, alot of the outdoor pond filters i see, say for use in "koi ponds" or whatever it is. generally only referring to koi fish however. are these safe t use indoors on a tropical pond with pacu?? does anyone use koi/pond filters for their indoor tanks??

and one other question, concerning bead filters. i see some that are more than adequete with filtration, yet they say X lbs of fish max. my 4 full grown pacu together will exceed the LBS rating on all but the biggest filters. does this really matter much??

a koi filter is the same as a normal filter, the manufacturers just didn't think that there would be people with giant tanks

A lot of pond filters say rated for a huge number of gallons, but in normal fish keeping they can't support nearly that many gallons worth of fish. Look for GPH instead of their rating. Look to get around 3-4 x as many gallons per hour then your tank volume. So look for around 5400 give or take some. You might be better off with a couple of large pumps and a large sump filter. If you go sort of light on the stocking you can get away with around a 2x turnover rate.

A filter is a filter.

i see what seem to be decent koi filters for several thousand gallons. figuring the filters wont filter what they claim, i was thinking of maybe 2-3 koi filters rated for around 3k gallons each. and only use them for mechanical and load them with bio-max

pond filters are extremely cheap on ebay for large ones. i dont honestly want to start messing with sumps, as its something ive never had before, and feel much better with can/bucket style filters for some reason. i also like the ability to backwash on alot of these bigger pond filters.
