Hanna KH checker is sweet!
I have the salifert Kh test kit and I was having trouble reading the colour or counting how many drops added. So I opted to buy the Hanna Checker and what a simple test!
Its soo easy!
add 10 ml tank water to cuvette, insert to checker, press button, wait for C2, take cuvette out, add 1 ML of liquid reagent, insert to checker, press button, multiply number shown by .056 and tada you have KH!!
For 58 bux you save your time and hassle counting drops and checking the colour.
