Total Alkalinity=0, yes zero!

Thanks Waterbear and The Goose. We will focus on the pH rather than TA for my neighbors pool at this point.

My Taylor kit actually has the base demand and acid demand test, I've just never used them because I've never had that problem. Waterbear thanks for mentioning that.

So it took 30 drops to bring the sample to the pH range of 7.4-7.6, so based on what the book says, it says to add about 18-20lbs. Based on what you said to add 2x that amount of borax--- so I've instructed him to add 38 lbs of borax into his 24K gal pool.

Thanks ---will provide updates later.

Waterbear you are correct about the trichlor tablets. He uses them all the time and I told him to stop using them because of the acidity and CYA---his CYA is 80, so I said use no more for the rest of the season. I told him stick with straight liquid CL.

Do NOT have him add 18-20 lbs. of Borax all at once!

Thanks to all that helped on this thread. I got my neighbors pool in order. It took about 40 lbs of borax in 24K gal of water in his vinyl IG pool to get the pH up to about 7.4. The TA is still around 50, so I'm going to have him add more baking soda to get that right.

You are welcome! Now, it is time to go swimming!
