I just recently had a pool installed and have been using Baquacil. I knew it would cost more and until today have not had any problems other than adding Sanitizer about twice a week. I bought a seasons supply of chemicals and went through all of the sanitizer in the first 2 weeks. Today I go out and it went from crystal clear to green overnight. I carried a sample to the pool store and they said it is algae and gave me some Flocculant to put in the pool, wait 2 days, vaccum, etc. They said it was most likely caused by the solar cover I installed 2 weeks ago and they recommend converting to chlorine or salt if I still want to keep the solar cover which I do. I was actually thinking about converting to the salt system anyway. The friends I have that have the salt system have no problems at all with anything. If I go with salt the warranty with Doughboy will be voided but I live on the beach so what parts that are going to rust will rust anyway and I will just have to replace them. The people at the pool store said they know others with a pool like mine that have converted to salt and have not had the rust problems. My questions are when I convert should it be salt or chlorine, can I drain my pool to make the conversion easier or will it wrinkle the liner, does anyone else have this problem with a solar cover, and if anyone has a better idea or ideas please let me know? Thanks
