I recently went to the fish store with some questions regarding my tank and the guy suggested I pick up Accu-Clear. He said it will have no issues with a marine tank. So i used it as he suggested and called it a day. Next day i noticed my issue had actually gotten worse and started doing further looking into the Accu-clear product. It was at this point that i noticed that it said 'for freshwater use only'. After seeing this i gave the same store a ring and spoke with the guy who sold me the product, just checking that this shouldn't be an issue. He basically said that it should work for both and theres nothing worry about, and if it doesn't help then has has other products which will. I just wanted another opinion as to if this will work in a marine setup? Thanks!!
