Pre Filter Question

[James0816]

I am having a hard time locating replacement sponges that I am using as pre filters for my HOB 30s and 10s.

Any suggestions or recommendations on where to find a suitable replacement?

Thx

i use the ac 110 sponges and cut them down.

i also use the aquaclear sponges and cut to fit. They are white though, until they age. I believe penquin makes a prefilter sponge that is black.

Laguna brand make a nice black sponge. It's round and comes with a strainer basket. I see them in all the petshops here.
