I have an in ground pool, size 16x35 with shallow end being 4ft deep and deep end being 8 foot deep. It has sat all winter without the pump on due to it getting out of kilter while I was on away from home working for 28 days. So I just cut off the pump and let it sit during the winter. I shocked it the other day with 15 lbs of shock and have gotten the water color clear again and have vaccumed the shallow end. My problem is the deep end is thick with algae on the bottom, it seems like about 6 inches thick. I tried to vaccum it and running the vac through it just stirred it up and had it floating and some comming to the surface. I have a polaris but dont want to run it until I have all this algae out of the deep end. My sons birthday is comming up in 2 weeks and my ex and I want to have a pool party for his birthday. Can anyone give me any advice on how to get all this algae out of the deep end so I can get my chemical levels back and ready for his party? Thanks in advance for any help I can receive.
