Hi. I have two commercial pools, well 2 and a puddle, that I am trying to take care of here in Tx. I have my cpo and afo and have been working with pools for awhile. I am having issues with oak pollen, as im sure as everyone else at this time of year. Pools are clear and have most of the pollen settled to the bottom. I am having a hard time getting it all vacuumed up. I brush and water turns green but after a few backwashes and a couple of days later it will clear up. my question is, is there actually any good chemicals out there that will help on getting rid of the pollen. Ive used Leslies in the past and am not a big fan of there chemicals. I dont have an auto vacuum and time restraints keep me from manually vacuuming as much as I should.
