its been a day since i done the pp just wondering what are the next steps as got told to leave it for a couple of days then do a water test and 25% water change and add filter booster, surely i should get another scrape done to see if its done the trick then leave it a good few weeks to build its filter bacteria levels up. also does this pp leave any marks on the fish in the pond. sorry about all the questions but no one locally seems to have much knowledge and want to learn as much as possible, thank you |
