I have Marine Pure Blocks in my sump. The top most block has corraline and algae growth on it's surface. The surface face of the blocks are exposed to the refugium light, and is semi exposed to air.
I'm wondering, if other aquarists who utilize ceramic blocks, clean them at some interval.
If you do...
· Why do you clean them?
· How do you clean them?
· How often do you clean them?
