Hi Paul

You fill a CO2 drop checker with 4dKH solution and pH reagent. This then goes green with 30ppm. More CO2, it goes yellow, less it goes blue.

This explains more... http://www.ukaps.org/drop-checker.htm

Making your own solution is relatively simple, or you can buy it from Aqua Essentials or The Green Machine. 1 bottle will last years.

Yeh, you can make it yourself but to be suse of accuracy and for relatively little money you can just buy a bottle that will last ages. Although, perhaps its just me that likes the easy option! :lol:
