I bought an overflow over the winter when I installed a sump / fuge.
(pics below)
I put FOAM in the overflow to prevent anything solid (food, fish, critters) from getting into the sump, and eventually into the Mag9.5 return.
Do You Folks Use Foam like that?
It gets VERY dirty catching a lot of flake food and I am sure it is a nitrate factory. I have rinsed out the foam occasionally. It is Very Dirty.
I would like to remove the foam, but I am worried that if I do, smails will clog/block the small hole, which constantly removes air from the overflow (picture below). If this hole clogs, air can build up and coud break the syphon.
