what do i do if my carbon filter for my filtration system has leaked into my tank water, do a pure water change(clean whole tank) or just try to scoop the carbon fibers out(i think thats what its called)
Just scoop them out. They won't release anything into the water so there is no reason to do a extra waater change. It is totally harmless.
PS: It is not carbon fiber (a very different form of carbon). Carbon fiber is very storong stuff but itdoesn't have the filtering capabilities. of activated carbon.
