Test Kits

[JDS]

I've had an email from API saying that the Gh and Kh test kits expire after 3 years, I'd imagine the rest of the range would be similar.

I use a freshwater master test kit by API. The chemicals can be purchased seperately if necessary. The kit wasn't very expensive, considering how many tests it can do.

This is what I have too.
It was expansive though, +$30.
