We just got our pool put in two weeks ago it has the sand dollar pump SD40 And it has that ionizer system also.they put one 40 pound bag of poil salt in the pool water as we filled it up. They said we won't need to put salt in ever again. This was a one time thing for new pools only. But they said we need to put a gal of bleach in a week. And that's it. They put 2 gals of bleach in at start up. Now our pool bottom feels slick and the side walls too. Our pool holds about 14000 gals of water. We run the pump about 8 hours a day. We talked with another pool company they said we still need to shock our pool once a week with shocker and that we need to put a floater in with chlorine tablets. Blue world pool says we don't need to shock it and we don't use chlorine at all other than a gal of bleach a week . So how are we to keep the pool clean and not slimy on the bottom and side walls? We never had a pool like this before just old cheap Walmart pools that last a free years then get a new one but the wife wanted a big big pool and it's just her and I. Anyway I don't care for the ionizer at all and don't know what to do. Our pump is a sand dollar SD40 WHICH I THINK IS FILL OF sand. Should we use shocker and chlorine tabs and forget about using bleach? Thanks
