Lowering TA with Dry Acid Or Muriatic Acid

[JohnT]

How do I aerate the pool?

Ed

A fountain, point the returns at the surface, or get a bunch of kids in there to splash around.

You mean just a plain ol' fountain like this:



And point the skimmer returns up to the surface?

That's all you need!

So my procedure to lower my TA is

1) Lower pH to 7.0-7.2. (Muriatic or dry acid are both fine) This lowers T/A somewhat.
2) Turn on the fountain
3) Lower pH again to 7.0-7.2, bringing T/A down some more.
4) Turn on the fountain again
5) Repeat 1-4 until T/A is in the desired range.

Is there a formula for how much Muriatic acid, or dry acid to add to reduce the ph? I.e. 1/4 cups of muriatic reduces pH by 0.5, or is it not that simple?

That's all you need!

Yup that's it.

In a 33,000 gallon pool, it is going to take about 26 oz. of muriatic acid to lower the ph by approximately 0.2. Don't try and get to your target in one dose. Small doses (maybe a pint at a time) added in front of a return jet slowly. Be careful not to splash any on you or on your liner. Also, don't breathe the fumes. Wait several hours to let it circulate, then retest and redose as needed.

It's been awhile since I visited the forum. I have had great success following the recommendations here. Glad to see it's alive and well.

My TDS got too high (could that be from using bleach (93% salt) all these years?) so had to drain a little more than half and truck in 10,000 gallons of water this morning.

My TA is high (210) on my first test. PH is 7.2. Should I wait for everything to settle down before adjusting. Or should I start lowering PH and begin aerating now? How do you calculate the amount of muriatic acid to lower .2?

Can you shock while adjusting PH (adding acid)?

Until my wife decides on a purty fountain, will this do the job?



Seriously, though, does this serve the purpose? Should I put more holes in the end cap... i.e. add more streams?

Ed

Yup that's it.
