Thank you PoolDoc & Watermom. I did pick up Borax this morning but I am a little confused. I've also read to use washing soda to raise pH so when do you use Borax & when is washing soda used? Is one used exclusively, meaning once you use Borax, you always use Borax?

Also, is 105 too high for CYA for my size pool? Should I discontinue using trichlor tabs? (I'm still shocking the water; today I used cal hypo)
