Envii Pond Equaliser – Pond pH Buffer Instantly Balances, and Stabilises pH, KH and GH Levels, Pond Ammonia Remover, Works All Year Round Through Winter - Treats 5,000 Litres (1,100 Gallons)

Does exactly what it says, always gives my KH a boost and keeps it there for 4-6 mths. Every koi pond owner should use this.

It works, but the winter tablets work better especially tablet form

Fantastic. Cleared the pond within a month after trying all sorts of other methods. The pond is now crystal clear so we will be using the product every three months as recommended to keep it clear. As we have a wildlife pond (and two cats who drink out of it) we wanted something safe for animals and amphibians. The a healthy population of newts and frogs in the pond shows that this product is not harmful to them. We would definitely recommend it.

Always great product from you

It's calcium carbonate in fancy packaging? Where do I see the MSDS to evaluate? Pricing seems way too high for such a small amount of raw cc

The first time I have used this product. I have a large pond with some lovely koi. This really works and after a 3 week week period the results are amazing.The water is crystal clear and the fish never looked better.

Ok

Does what it says it does. Good product
