As you people know Im starting my saltwater tank and have my RO running and my 46 gallon is almost filled. I just started up my Canister filter, powerhead, and heater and as I turned on the filter, that has been cleaned the best I could with hot water, I noticed really small white wiggly things moving around. I had seen them in my freshwater before. I haven't added the salt yet but are they harmfull and will the salt kill them? Also what are they?
