I was using Jungle labs 5in1 quick dip testing strips to test my GH and KH. When I ran out of strips I bought a TetraTest water test set. The strips had GH and KH in PPM, and the TetraTest kit has them in "# Drops". How do I convert the ppm to "# Drops"? I tried searching for the formula but I just got more confused. ops:

Doesn't the kit come with some sort of colour scale with ppm listed?

Whoops, actually I posted faster than my brain was working. You can enter the number in Chuck's calculator and it will convert the measurement from degrees (# of drops) to ppm. ops:

29g Eheim Classic 2213, community, heavily planted, 65W CF, 2x Hagen CO2
20g Fluval 3 Plus, nothin' but shrimp & snails, 65W CF, Hagen CO2

Divide ppm by 17.8 (or 17.9, depending on the reference) to get dH.

The number of drops = dKH or dKH. To convert from dKH or dGH (what you understand to be number of drops) to ppm, multiply by 17.8. To reverse just devide.

Just a side note 1ppm = 1mg/L
