Need someone to proof check my math on borax and acid..

[Guest]

The Muriatic acid I bought is 14.5%.
Pool is around 10,000 gallons.

Current Borates: 14

I am thinking I need about 424 ounces of Borax and 436oz of acid.

I'm coming up with this by using the poolcalculator.com and adjusting for the lower muriatic acid percentage.

Am I in the ball park?

I bought 4 gallons of muriatic acid, and only 4 boxes of Borax, before learning I'll need another box and a half.

If the muriatic acid is really 14.5% then you did your math right. You do see unusual concentrations of muriatic acid sometimes, but 15.7% is much more common.

Muriatic acid has been difficult to find here in Denver. I've only seen it at Home Depot and it comes in boxes of 2, 1-gallon jugs. I suppose it might be at Lowe's, Ace, etc., but I've never asked them.

I've asked my two closest pool stores and they don't even have it.

Thanks for your proofing my numbers.
