white flakey substance in pool HELP
I had a pool built going on 2 years ago in FL. No screen, salt cell, cartridge filter, basic pool.
All has been well. Recently, I have noticed a gathering of small, crystal like substances in one spot in the deep end. They are just laying on the bottom. If you stir the water they go all over the place. They are not stuck to the bottom.
If I vacuum them, they come back in a couple days. They are very brittle. They look very much like the calcium buildup you get on the blades of the salt cell, but they dont stick to the pool. they are just laying there. If I carefully take one out of the pool and dry it out, if you handle it it breaks up and turns to what salt would look like.
My pool water chemistry looks right on per the local PaP. No one has a clue what it is. Any advice? thanks!
