I never did identify the strain. I have upped my cleanup crew with some more variety to see how that does. Was down to mostly trocheus snails and a few mexican turbos and astreas. Turbos seem to eat it but not all the way to the rock. Also trying a pencil urchin. Wanted to add a couple tuxedo urchins but were out of stock.any update? have you identifies the strain? looks like Callithamnion
It doesn't seem to affect anything, just a little unsightly.
