Hello Everyone:
I recently had a new inground plaster pool installed in August of this year. I live in southeastern Pennsylvania. I had kept the pool opened until Nov 1st because I wanted to maintain the water balance ,especially the PH for as long as possible and allow the plaster to cure. I was having to dump in muriatic acid basically every other day to keep the PH down in the 7.6 range. All the other numbers were good. I was concerned about closing the pool and having the PH high for 4-5 months. I asked the pool builder about this and they basically said there is nothing else I can do and that everything would be OK. So I closed and winterized the pool on November 1st. I just took a look under the cover and tested the water and have a couple of questions.
1. The PH is now around 8.2 , and the alkalinity is 100. Do I need to address this somehow?
2. The day the pool was closed it was very windy and now there are a good amount of leaves on the bottom, is this OK? or will it stain the plaster?
3. There is a white residue covering the bottom that looks like DE to me but the pool company says its the winter chemicals they added, does this sound right?
Thank you for your help.
BTW- Pool is covered with a an Anchor Mesh Cover, that's supposed to block 95% sunlight
