Alkilinity (dkh) Test Kit?
My current test kit is just about done and I'm thinking of trying something new. I was considering a Hanna HC checker but they (all HC checkers) have increased in price by almost 45% in the last year. Now around $100 a crack, they're still under $50 in the US so it can't all be blamed on the exchange rate.
Anyway what does everyone else use for alk testing? Are you happy with it and how often do you test please?
