Help please!! Need help choosing filtration

[dan198811]

Hi all I'm getting back I'm to the hobby and I'm stuck on which filter size to go for. I've got a 90 litre tank with (4) 2" koi and I'm looking at the "all pond solutions" range. They do a 450 l/h for tanks up to 90 ltr or a 600 l/h for tanks up to 110 ltr. Which do I think would be best??

Thank you

Filters are almost always over rated. You may want to go for something rated even higher than 110L. Most experienced folks will tell you take the number they give you and double it.

Thanks for the reply. I was rushed into a decision and ended up going for the 90 ltr 450 l/h. I will have to wait and see how it performs when it arrives and if neccessary run it with a 2nd smaller filter.
