I balance it to 7 with solution. Then check my water and it says its 7.22 but when i check with the good ol drops its about 6.5 or 6.6 and sometime it is even way off more. and have to adjust it everytime...
Is this a automatic pH meter?
The only reliable way to measure your pH is by using a test kit. The automatic devices must be adjusted and set at least as often as the manufacturer recommends.
Your pH should be between 7.2 and 7.6. Your Alk should be at 100 (between 80 and 120) Get the Alk right before you try to get the pH at 7.2 or 7.4. These changes you are making should be measured over a number of days not a number of minutes, by the way. Alk 'buffers' pH and prevents pH 'bounce'.
Does your filter system run 24/7? Point of interest, most commercial pools should have a 8 hour turn over rate and run 24 hours a day for best results. Spa's should turn over on a 2 hour basis.
I don't know where you are writing from, the acceptible pH in the USA, generally, is 7.0 to 7.8. 7.0, while not really bad, is more acid than most swimmers can enjoy.
Other considerations: Your calcium should be around 250/300 ppm. Outside pool? Cyanuric Acid should be around 70 - 80 ppm. CL should be around 4 ppm. If you are using Bromine, the Br number is 2 X the CL number. By the way, Bromine is about 2 X more expensive than CL. Might you be using salt and making your CL? Salt should be 3200 to 3400 ppm and you should monitor your CL and adjust daily to get your 2 to 4 PPM cl. You MUST protect this CL with Cyanuric Acid.
I hope you find this information helpful. The courtesy of a positive vote will be appreciated.
