Where are you trying to keep your pH? My guess is that if you let your pH rest at 7.8, you will use a lot less acid..
I would dose every day for a couple of weeks and see how well it works and how much effort it is. Then you will know the answer
Hi thank you.Your TA is the problem. The pool industry recommends 80-120 for Alkalinity, this is so they can keep selling you acid and buffer. For a home pool, that does not use an ORP sensor, you can let it drop to about 50, and that will usually mean a lot less pH movement.
Another thing that causes the pH to vary, if your pool has, water features, running them can increase pH through aeration.
I had similar issues initially. I was able to reduce acid consumption and frequency with 3 changes:
I never had to add acid daily but it was almost every other day. Now it's usually once per week.
- reduced run time for spill-over (reduces aeration which causes pH to climb).
- added borate buffer.
- operate in the high end of the TFP pH range while keeping a close eye on the CSI calculation in Pool Math. Staying slightly negative and never outside TFP recommended range. This seems to be working well for my swg cell. After one year of operation the cell has never been cleaned and looks brand new. Maintained 40% power since installation.
I hope this is helpful.
You can improve pH control with addition of boric acid or borate compounds. There are many other less tangible benefits but I can't say I've experienced them. Please read more here and let us know if you're interested and have any questions.What are borate buffers?
Thanks Chris. I’m going to research this. We have dogs that get in the pool quite alot so that is another consideration.
