No, add clean-up crew as you see algae. If you start to see algae on the rocks add two trochus or turbo snails. If you see algae in your sand get a few narsarius snails. Brittle stars are a little trickier they will clean inside the holes and crevices around the tank, which you can't see into so add one around 2-3 months in, alternatively you could get a group of micro brittle stars, which will do the same, but they can get in even smaller crevices.So when I get the tank up and running again I should get Nassarius snails and a brittle star or an Urchin?
