A pond water
purifier is an excellent choice if you want to keep a healthy
pond. While adding a little tap water at a time is OK for your pond
and its inhabitants, adding a lot of tap water (without running it
through a pond water purifier) can be harmful. This is because tap
water often has additives, like chlorine.
Chlorine is harmful to fish – it can affect their gills and
even lead to death. This is one reason why a pond water purifier can
be an excellent choice for your pond. You can even hook up a pond
water purifier to your float valves. In this way, you can be sure
that all water enters you pond is pure water.
