frustratedmom you have been a great help , I will forever listen to your pool care advise however the Bleach seems to be not as economical as the puckes :?: :?: , I dont know but i will go back to bleach, the pool does look great, it got a bit cloudy today, kids were in there for a long time and the cloudyness showed up after I added 4 Lbs of Borax. i will post #s on Thursday , wow we have major storm here winds and pouring down rain, should have waited on the Borax and bleach
