Hello again everyone! We had an awesome swim season last year after converting from Baquacil to BBB. Pool looked great all winter.....had covered it in October, but had major winds that ripped the cover off in December, so we just left it open after that. Water was crystal clear until early March....when the pollen bomb exploded! The pollen is so thick on the bottom my cleaner can't get across the pool twice without stopping and having to be cleaned. It is very difficult to vacuum with the regular vacuum with the fence around the top. Have been trying to brush, but that is difficult as well. Just tested and CYA is not reading, so I know it should be less than 20. We did have to replace some of the water from closing (CYA last summer was 30) so not sure how much the replacement would affect the CYA.
CYA < 20
Should I just use a CYA of 20 and shock to 10? Can I go ahead and shock even though I can't vacuum yet from the pollen. Or does the vacuuming really need to be done first? I have no idea how I'm going to do it without getting in there....which I really don't want to do! We had alot of pollen last year when we coverted, but nowhere near this bad. I'm really not sure what to do. I'm also assuming some of this could be algae. Thanks for your help!
