I use the a.n.other one and it works fine, blue with no co2 and a nice limeade colour when co2 is going strongSim222 said:thanks I have the API master test kit which includes High Range (no good) and a.n.other covers PH 6.0 to 7.6 is this other the one that is likely to be ok - as far as i can see API don't do a PH test call 'low PH'
many thanks for you help!!

i used a mixure of De ionised water and my tank water at various concentration to get 4Dkh ... total cost £1.00
The whole point of using 100% pure water with BiCarb added is that the BiCarb is the only thing that will react to alter the pH.
