I have no idea. The turbos I got online, were absolutely tiny! Can only see a couple around on the rocks.The question is why isn’t the clean up crew eating the algae? Are they sick and dying, is the algae growing faster than the CUC can harvest it or do they find the algae not palatable, possibly because cyanobacteria is growing on the algae? What do you think?
My trochus seem to prefer being on the glass, I do occasionally move them onto the rocks but not really making a dent in the hair algea.
Like it's not extreme right now, I can only really notice it when the lights are off in the morning. I'm sort of just trying to get it under control BEFORE it gets to the point of wanting to shut the tank down
