What is the best way to clean my 10 gallon QT tank after treating Ick? Do I need to throw out my filter cartridges? Also, I know that I need to leave my DT fishless for 6-8 weeks. The only livestock I have in it right now are 2 peppermint shrimp, 1 emerald crab and hermit crabs and snails. How high can I raise my water temp without hurting the livestock?
