So your PH tester is reading correctly then? distilled waters ph starts to drop as soon as it is exposed to air, so i have heard.

after all the messing with the first one yes, ide say the meter is correct, so far :r: gona have to look into what you said about it droping in ph. but then if tap water changes over time it could be right.

distilled water is different from soft tap water. There are no minerals in distilled water to buffer a drop in ph.

UPDATE! UPDATE! UPDATE!
well its been a few weeks since i got the new meter back and have been using both the meter and chemical tests. the meter seems to be correct so far as although still color blind :l: they are very close to each other in reads. the only problem with the meter is that i have to constantly test calibrate it every 2nd time i use it. does state in the instructions this has to be done to keep it correct. don't know if all meters have to be calibrated like this all the time. have been checking the web for meters and there is a few for checking almost all stats, pH,nitrAte,nitrIte, ammonia,gh and kh etc. but costly and can only find them to test pond water at the moment and costly €400 has any one else seen these on the web?
