Yes, I know. I will be going to BBB after all tabs are gone. I just hate buying something and not using it. LOL

Anyway, does anyone know if Leslie's Pool Supplies tri-chlo tabs have impurities in them that leave a "dirt" looking substance on the pool bottom? Also, I just cleaned the surface with the net, then ran the manual vacuum, and noticed lots of very small black "things" floating while vacuuming. I am thinking it is impurities from tabs. Anyone else?

Thanks
Jeff
