Hi
I went away Friday morning leaving my husband with simple feeding instructions only, and have come back to the sand absolutely filthy. The tank isn't overstocked and I'd done a 75% water change before going and a thorough substrate clean.
Is this normal or does it suggest the filter is ineffective? (The filter is good I think, it's the juwel M bio filter that came with the juwel 240 tank - just thinking that maybe I need to clean it more, I've not cleaned sponges a lot so far as it's a newly cycled tank and I've wanted to grow the bacteria so only done a couple)
