filter

[j@mie]

hi guys, i have a 4ft x 4ft x2ft which i believe is 75 uk gallons currently stocking 6 small koi carps, i have a fluval 4+ filter and a fluval 2+ - but they arnt efficient enough to handle the waste but i cant afford much.

i was thinking, at my local fish shop they sell the pond filtration boxes quite cheap which include about 4 different levels of filtration before being returned to the pond, and tbh this is what i need, but how to i modify 1 of these boxes to work on my tank? obviously i need an inlet and outlet which it will have but what do i need to purchase in order to start the syphoning of the water into the box, then pumping it back out into the tank?

plz advise asap many thanks

Ummmmm! 6 koi in a fish tank not a good idea, whith them being inside, the water will be warmer which speeds up there metabolic rate which makes the grow faster, so they wont be in there for long before they will need to be rehomed.

I kept koi in a tank myself a long time ago, and found no matter how much filtration i put in it was never enought, they like to root through the substrate which ment the water was always dirty.
The only way around it with out spending an arm and a leg on filtration is lots of gravel cleaning, scrubing and water changes.

As for pond filtration, i cant remenber exsactly, but it think its something to do with the fack that the water is forced through aquarium filters under presure, which gives a high turnover, and more eficent filtration, than one of them box pond filters that works with gravity

The pond filter would have to be above the aquarium for it to work unless you got a presurised one

EDIT if its 4ft*4ft*2ft Volume 905 l./199 gal.
