Swapping to BBB but what about CalHypo

[RobDHW]

Ok, I've got my questions mostly answered. I can just buy HTH Calcium Plus at WallyMart to raise my calcium (found that out this morning) w/out having to buy the CalHypo shock.

My pH is WAY low (6.8 or less) & I bought Borax, which is going to be added as soon as I fire off this post & figure out the right amount.

Carl: as for the heavy lifting - a friend of mine has the best t-shirt "I'm not real bright, but I can lift heavy things". I'm all over the lifting. Amzingly, I think I can learn too (see - now I'm on the BBB plan).

So, the numbers (from a HTH test kit - until I get the "good one") :
Cl - 10
pH 6.8 (adding Borax)
TA - 70
Ca - 70 - still need to know what it should be - must do a search when done
CYA - 100 (yanking pucks out) (test strips LIE)

You folks all rock! THANKS!

Calcium level between 200-400 is what you should aim for.

Is your volume 1100 or 11,000 gallons. I think the 1100 is probably a typo in your post above. If it is 11,000, I'd start with a half a box of Borax. Give it a couple of hours to circulate, then retest and redose as needed.

Yes, Watermom - I can't type. 11,000 gal (although, I want to recalculate... today is pool maint. day).
I went to poolcalculator.com and figured out that I'm going to add 4lb baking soda, since my TA can be raised a bit, then I'll add some Borax. Test again. repeat.
I also need to add serious calcium per the calculator. I bought some, which I will add, then once again test. Repeat as necessarry (or however it's spelled).

I'm so happy that I found this site, from the bottom of my wallet and the top of my brain.

Do the Borax first. Low pH is a much bigger problem than low alk. And, actually, TA of 70 isn't bad.
