I recently dosed chemi-clean in my 5 ft 125 and put 13 scoops for a bad cyano outbreak. after 48 hours I noticed that the cyano was entirely unchanged since I dosed it, I don't have any other form of mechanical filtration, no filter sponge or carbon, just a protein skimmer. I put air stones and left the skimmer on without the collection cup so nothing was collected, but does a protein skimmer still collect stuff even without the cup? I am ready for a water change like the product instructed, but should I do the water change and redose, or should I put more chemi-clean in the tank and not have the protein skimmer on?
