Coarse Foam

[Aqua sobriquet]

It doesn’t seem to do much in my filters. I have coarse, then medium then fine then Bio Media like Siporax or Substrat Pro. The only things that catch the detritus is the fine foam and bio media. I’ve got to fill up the space in the new filter that’s on its way and I don’t need any more than a litre of bio. If I add more fine foam I think the filter will just get blocked more quickly. Any thoughts?

Hi
The coarse foam is fine to use.It will block slowly and alow greater flow.In time will start collecing mulm its just slower process .
I do most of mechanical filtration out of my main filter body(large prefilter sponge on the intake) and rarely open it.

Something like this is cheap and won't block flow: Clearance Sales - Allpondsolutions

Simlilar to the plastic media Oase supplies in the Biomaster, but not hideously expensive to buy like Oase Hel-X is in small quantities.
