Hello guys ! My 110 gallons tank is suffering from a serious algae problem. I have a sump with full of chaeto in it and an oversized skimmer, but it seems like nothing can compete with this Green Turf Algae stuff. They are growing everywhere on the sand gravel. I'm thinking of spot treating with H2O2, but too afraid to use because I think that it will also affect the Refugium with Chaeto down below. Any thing will eat these ? Urchin ?. None of my tangs are touching it, neither the snails or hermit crabs.
