Hi - I've been a TFP disciple for several years now. Since converting to using bleach, our water has been crystal clear and algae is non-existent. However, I battle high alkalinity every year. We have a 18 x 30 pool with about 16,000 gallons of water from our well. I am constantly lowering the pH to 7.2 to get the alkalinity down. We usually start the season with alkalinity at 140 and I gradually work it down to about 100. Can't seem to get it lower than that. Suggesions would be appreciated. Thanks!
Perennially high alkalinity

Or maybe I just shouldn't be worried about it per this info from Pool School:
There are two reasons to lower your Total Alkalinity
1. to slow down the rate that the pH rises or
2. if high TA is contributing to a high calcium saturation index (CSI) which puts you at risk of calcium scaling.
You do not need to lower TA just to reach a target number. Make sure you actually have one of the above issues before lowering your TA!

CB, if your pH isn't rising exceptionally fast, I wouldn't lose sleep over it. Each time you fill to top-off the pool it goes up, so it's a constant battle. Allow the pH to hit that 8.0 mark then lower the pH down to about 7.2 when you're ready. Slowly but surely it will sink ..... until you add new water.
