Should I just leave my sump alone?
All the algae is floating on top. I put a rock on it but the algae is so thick it just holds the rock up out of the water.
Everything is fine with my display tank and the water chemistry is right on.
I think if it isn't brook don't fix it?
Does your sumps look like this too after 1.5 years?
I read sump algae die of is part of the processes.
There is no light getting into the bottom of the sump?
