Foam Filter Block 4" x 4" x 8"

In stock

These Filter Foam Blocks have a small hole drilled part way down the centre which is ideal for the centre of most pump pre filter cages.

This can be easily cut down to size if required.

These Drilled filter foam blocks can also be used to make up your own under gravel pond filter via a spider or matrix of foam blocks linked together with pipe work.

They are ideal for trapping fine particles and so help polish the water and aid biological filtration.

These work well with tthe Kockney Koi Pipe Cage we stock
