Very good ,easy to use ,and the right result

If you keep pond or cold water aquaria this additive should be in your arsenal for regular upkeep and maintenance. Used as described will assist to stabilise pH spikes as well as other benefits. Used along side a reliable test kit.

As expected

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

It is very ease to use, no chemicals help with water quality, I will use it next time brilliant

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

Utiliser dans un étang de 10000 litres.

Funziona alla grande. Bisogna seguire le istruzioni alla perfezione. Ora acqua bellissima.
