Can the tap water be filtered directly after the drinking water purifier is filtered, and the tap water can be changed directly to the fish tank after being filtered by the drinking water purifier
You can not change the filter, water exchange is the premise of not more than 1/2, you are in the sun to sterilization, but no one can achieve 100% sterile, improve the resistance of fish is fundamental, tap water chlorine to fish is harmful,
This method is an old man who has kept goldfish for ten years. He shared it with me, so others can sell a lot of small goldfish every year.
l, but things have a limit, you do not change the water more than 1/2 of the fish is not only harmless, but also a little better, chlorine can also sterilization. I have been selling ornamental fish for many years, and I have some experience.
