yep. i have already taken all the rocks out and scrubbed and dipped them in clean saltwater twice. they were beautiful and clear for about a month. this time i just said **** it, I’ll fix it when I upgrade the tank.I’ve been there too, honestly I have kinda learned to live with it. I just pic the clumps out when they get big enough, and strangely it seems to be the worst around my overflow and in my refugium.
