I think it depends on your fish. We put in half a slice for 2 fish before going on vacation for 4 days. The tiny pieces looked pricked when we got back but they were alive so I guess it worked. I left it to see what happens, it was there for 3 weeks with no change. Over time it turns whitish on the outside but doesn't dissolve, which is strange to me. I am deleting this. I have no problems with cloudy water. So I think it worked, but I think my fish was just starving and didn't eat it.
