hi I have got a small amount of hair algae growing in my tank and was wondering best way to deal with it. Also I have noticed that I have a sponge growing in between my fuzzy green mushrooms, I have had to feed them and turn the AI prime one white to get them to close to take a pic. I have a couple of small sponges but this one is different. It has tube like chimney structures, only 3 but it’s looking like it’s getting bigger. Help and advice would be grateful.
