GH for Koi keepers (Water Hardness)

GH or General Hardness is one of the less tested parameters in the Koi pond system as it is generally within an acceptable range when left to its own devices. It does however have a preferred range and it is important that you stay within that range.

In this video I talk about what GH is, how it varies depending on your source water, what range you should aim to stay within, hard water & soft water, and what effect it has on your koi amongst other things.
