I’ve had thick tough as nails turf algae I’ve been battling for some time. I’ve tried many things to fight it. Peroxide (works in spots, but can’t get it all), tuxedo urchins (manually removed areas hoping it would come clean up the bits left behind, they don’t touch it), foxface fish has no interest in it. Tried a 4x dose of fluconazole. Don’t affect it at all. The main problem rock is unfortunately my biggest rock at the base of my scape. So not easy to “just pull out the rock and kill it”.
I did have an idea though. What if I blackout JUST that rock with some black plastic? I’m thinking I could cut a piece of black plastic sheeting and cover the algae for a couple weeks. Is this a crazy idea? Anyone done something like this before? I know people black out their entire tank with plastic wrap to kill algae, but an individual rock? My only main concern would be the plastic I use not leeching anything harmful into the water.
My only other option at this point seems to be a massive rescape involving pulling all the rocks out and removing the affected rocks.
