I’m new to this group and aquarium keeping in general. We have a 32 gallon bio cube, with 1 clownfish, a GSP, a torch coral, a turbo, a trachus, and 3 nassarius.
We’ve been doing regular water changes and everything seems happy and healthy and growing, including what appears to be a moldy looking growth on the rocks and sand.
My water quality is pretty on point except the KH
tends to drop.
Do I need to attempt to get rid of this moldy looking stuff. I have another clown in a QT tank that I intend to put in the main tank in about a week.
