So i searched the threads and did not see anything about this. Forgive me if i missed something.
We have lived in (rented) this house for 5 years. It came with a guy who comes and services the pool every Monday. I don't really get involved with it, other than to make sure to tip him once in a while. Other than rinsing the filter out in my yard (sigh) (twice) after i asked him to take it to the street, he does a fine job. I love my pool, even though i can only use it 4 months of the years (un-heated). I am in it every day i can be.
However, this summer i noticed some spots on the bottom of the pool . I also noticed that the paint seemed to be eroding at a faster rate than normal. He (pool guy) had not noticed this, at all. So these spots are in the shallow end and about the size of a quarter. There may be 20 of them. The closest i can come to describing them is that they look and feel like warts. Really hard warts. It appears that they came and set up shop, multiplied a bit, but now are not multiplying, but are not going way. The paint, however, continues to chip away.
When i asked him (the pool guy) about this this morning, he recommended draining the pool and giving it an acid wash. I know nothing about this and am going to have to help my landlord figure this out. Can you, TFP experts, help me help him? I do not relish paying for 20,000 gallons of water in drought stricken California, now or ever.
Thanks for your time,
