I have had my pool for only one season, and check chemicals regularly, but have found that the only chemical I need to constantly put into my pool is ACID to lower my PH. Last season (my first), after adding salt, CYA and CH, I hardly made any adjustments to them all summer. I would like to add an automatic acid feeder to my system, but have the following questions.
1. My strong preference would be to have a feeder that reads the PH electronically and calculates the necessary amount of ACID to add. I understand that a fixed rate pump would probably work fine, but I would enjoy having an electronic reading of PH to compare to my own calculations. On the other hand, if the calibration went astray, I would like to be able to use just a fixed rate addition of ACID. Is there any system that would give me the option of using its calculation of PH to make the equivalent addition of ACID while also permitting me to forego such precision and instead have it drop a fixed rate throughout the day.
2. I have an AQUALINK 2.0 (with free relays) and would like whatever system I get to linkup with it so that I can monitor PH from my phone and compare it to my own testing without going to the PAD to see its measurement. I would also like the ability to increase the fixed rate via my phone.
Below are some pictures of my PAD (they not the best pictures but hopefully they show enough). Thanks for your help.
