Hi -I have had my tank up and running about 4 weeks. I have the Kent Marine Bio Reef, around 94 litres with 10k live rock, some live sand, a few turbo snails, red foot hermit crabs and algae snails. All my levels are perfect but the last 2 days I have seen a large outbreak of tiny white "pods" covering the glass. I have read elsewhere that these are generally good for the tank but also read that I should empty and start again. Help!
