Hope anyone can help.
I am taking care (involuntarily) of my sisters pool.
As you can see on the pictures it has turned quit green lately. The chlorine values have been good all along. PH was a bit low all summer but seems to be good now. Alk is good too. Last week when I went to check on the pool it turned out the almond tree next to it had decided to shed allot of it's leafs into the pool. It looked very dirty but surely not green. It was all sitting on the pool bottom. I scooped out all the leaves and decided to leave the pool for a few days so that all the dust could settle. It did and I started to vacuum the pool. Half ways through I did a backwash which went good but then I forgot to rinse. When I turned the dial back to filtration a black cloud came out of the 2 jets. (Is this because I did not rinse?) I think that all the dust I had vacuumed up before went straight back in. Again I decided to leave the pool for the dust to settle.
Yesterday (4 days later) I went back up and it looked like in the pictures. My friend thought it felt slimy but I don't think it does really. It also seems to be just on the floor and it looks like an even layer of (greenish) dirtThe walls are clear of any green stuff. I also took a glass and filled it with pool water and it looks crystal clear. Al chemical levels seem to be good.
I went to the local pool store and the girl in the store sold me a pale of granular slow release chlorine. She was convinced that that would solve the issue. I did tell her I had algae in the pool. She said "NO" to shocking. If it really was only sitting on the floor of the pool then this was going solve my problem. I have trouble with this approach.
Should I just try to vacuum the pool (maybe on the waste setting) and see what happens or do you experts think it is indeed algae and treat with chlorine?
Thanks for taking the time to read my lengthy post.
