How much is the TDS increased if Borax is added to 50 ppm

Chem Geek,

Thank you, and yes you were correct I did have some (maybe lots according to the Chlorine usage) black and mustard algae which the chlorine is eating at an alarming rate.

My credit card is now up to over $50 for Wal-Mart's Ultra Bleach. I keep going back there so often they are beginning to look at me strangely. The plaster is beginning to look like the day it was put in, although the pool is still cloudy. Maintaing the level at 40 ppm. Did have to use a stainless steel brush to break it up as the nylon did not work; lost about 10 lbs scrubbing my little pool in full sun, would hate to do this to a larger pool.

Will let you know the full story once it is over; summize several dozen Ulta Bleach bottles more!

Aloha
