I restarted my refugium a few weeks ago and the Chaeto is growing fast and doing its job but I am getting an abundance of hair algae in the fuge. The fuge holds 30gal of water and holds no substrate or rock. I am looking for recommendations for CUC for the fuge. I have heard Mexican Turbo's, Urchins and Sea Hare's are good for hair Algae. I prefer not to add a Sea Hare due to the toxin they can release. I also understand the blue leg hermits are also good but I am not sure if they can climb the PVC sidewalls. Can they hold onto the hair algae and climb while the eat?
Appreciate any recommendations.
