What are causes of alkalinity dropping? I’ve noticed the past week it has been going down a bit. My ph is also going up, I assume b/c of this. We’ve had no rain where I live for at least a week. The only thing that has changed is that we are now using a solar blanket every night and most of the early morning. Also, there’s lots of leaves now falling into the pool. It’s a SWG about 15,000 gallons. Should I add some baking soda to bring alkalinity back up a bit? I’m only using test strips for the time being so I can’t get a really precise reading but looks like just at about 80. It’s a new pool and I’m learning as I go. Thanks.
