Seeding Filter Question

[The Duke]

By "stuffing" a new filter full of old cycled filter media would ther not be a danger of drastically reducing the flow rate of the new filter?

Obviously you have to be careful not to do that. The best way is to remove some of the new media; that can gradually replace the old cycled media over a couple of months.

Ahh right. So this would require a sort of DIY cutting and fitting job I suppose?

lol, yes, usually. I've often said, I don't think I own a single filter sponge that is still in one piece!
