Does the water in the tank always relate to the washing bag
quarium filter using a filter bag once every three days to wash, the water in the cylinder is always white, if you are completely clean, every time is related to wash the filter bag didn't si; If it's not cleaned, it might be a residue of washing powder, which is a bit of a relationship, but it's not likely because the fish will get sick or die. I think it might have something to do with the fish feed you feed; Or the recent water bleach.
Don't wash so often, wash once in a dozen days with the urn, after a few days water is good.
It could be fiber in the filter bag.I hope my answer will help you.
