Hello! I am aware that microalgae often is something that you do not want in a reef aquarium, but I personally like microalgaes and other algaes as they inhabit beneficial microorganisms, and contribute to nutrient cycling. I recently got this massive diatom bloom, which was nice but there came to be too much, so I got three small red foot hermit crabs to help control it better. Its been 4 days since I had introduced them and my microalgae population has nearly been eradicated, and the tank is spotless which I am not aiming for. My hermit crabs eat algae nonstop, and I am wondering if there is a way for me to slow down their eating pace, or perhaps give them other food to eat? Just to help get my microalgae growing again.
