So with this heat we have had here in Sunny CA, it seems like there are more
and more of these maybe 2" around little bubble like things on the bottom of
the shallow end (3.5'-4.5') of the pool. Last year there were a few, 6
maybe, now I'm up to 20+ of them. You cannot press them down, so they do
not seem to be flexible.
What are they?
What causes Them?
What should I do about them?
I believe it was installed in 1991? We are new to the house/pool (10/2003),
so I'm not sure who installed it, etc.
How long to Fiberglass inserts last? is 15 years a long life for these, or
I'm wondering why new ones are sprouting and why only in the shallow end.
Might you or your kids be damaging the bottom with a hard object. Maybe

Its not the gunnite (sp?) type, I think its a Fiberglass insert.
I did have a pool guy out once, he was pissy they we didn;t retain his
services after we bought the place. I told him I didn't know he was the one
who maintained it. Anyway it checked out fine. He showed me how to clean the
filter, etc and the Chemical part I knew about. The bubble were not there
at the time.
