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!!
This won`t work I`m afraid. 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. You are using tank water that will have all manner of reactions going on, altering the pH in the drop checker.ziggy_909 said:hi i have just mixed my own 4dkh solution ... i hope ..!!!
i used a mixure of De ionised water and my tank water at various concentration to get 4Dkh ... total cost Â£1.00
cheers for the input.... is it possible to uses biCarb of soda ( baking additive ) and if so at what concentrations....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.
Seeing as it's simply a change from blue to yellow then pretty accurately. You're very correct about reading the balance more accurately but Sodium Bicarbonate absorbs water once opened so you don't know quite what concentration of it you're adding with your scales!celkins said:But how accurately can you differentiate the colours on a chart, as opposed to read a balance...
