I go through about a gallon a week. It's a plaster pool that is still relatively new. I usually go to the pool store and get a box of 4 gallons and don't let them sell me anything else. I'm good for about a month. When I test my water and it's above 8, I add about 1/2 a gallon and test the next day. It's usually down in the 7.6 range and by the time I test again in a few days it's back up around 8 so I add another 1/2 gallon. Sometimes, I feel like I am the only person on the forum who isn't using measuring cups.
I am a relatively new pool owner. I have a Saltwater Generator that has been off through my relatively short time of ownership (6 mo) due to it being winter time. I have a 12,000 gallon pool that needs about a half gallon a week of muriatic acid as well. I don't use measuring cups either. It's pretty much always a half gallon that does the trick, unless there was a significant amount of rain that week. It was replastered about 4 years ago. I keep the TA around 100. The Ph fluctuates the same as above. I go from 8.0 down to 7.4 back up to 8.0 every week. Is 1/2 gallon a week too much to add for this size pool? I feel like I am missing something else.
I'm also adding about 5 lbs of baking soda every other week to keep the TA at 100 to counteract all of the muriatic acid I am adding.
I'm adding bleach for chlorine while the SWG is off and try to keep it around 3-4.
Is there anything I could be missing or is this just normal for some pools? I live in Fort Worth.
