It appears that we are getting some calcium buildup in our pool. We have 2 large sun shelves that I first noticed this on, but if I pour a little acid on the shelf, and scrub it with a brush, it goes away.
In the picture attached, you can see what I am referring to, but this is in the deeper ends, so it is hard to target.
My question is, can I lower the PH significantly for a short time, continue to brush the pool, to get rid of this. My thoughts are the lower PH and brushing will help break it down, but do it before it becomes an issue for the finish.
If there is a solution, other than draining the pool and doing an acid wash, please let me know.
Any help is appreciated! Thank you.
