Has anyone had a problem with small pieces of chaeto breaking off and clogging pumps? I haven't changed anything. I have a small area sectioned off in my sump for the refugium. It is in the same section as my skimmer. Lately my skimmer stops making bubbles and when I take it a part the chaeto has clogged the impellor. This is a completely new problem in the last couple of weeks. Any ideas how to stop this from happening? My refugium is made out of egg crate. If I covered the refugium with cheese cloth, would that work? Thanks for any problem solving ideas you may have.
