Ph 6.6 Alkalinity 50 HELP

[timmie]

Hi everyone, and thanks for all the advice.
here are my new numbers.
Free Chlorine 17.0 I shocked the pool
Total Clorine 0.0
Combined Chlorine -17.0
Ph 7/0
Hardness 170
Alkalinity 130
Cyanuric Acid 30

What should I add now to bring the numbers where they should be? I bought A&H soda wash today. I am not sure how much to add.
Another question is. How do I maintain my pool while I am away for a week?? Do I put alot of javex in it?? I am not sure what people do when they go away.
Thanks

OK,
Those numbers change everything. Do NOT add either Washing Soda OR Borax! And don't add Baking Soda either.

You still need to raise your pH, but you can do it without increasing your Total Alk level (already at the upper limit) by aerating your pool. You can point the return at the surface, toss in a bunch of 12 year olds (in old suits), get a sprayer or fountain, and leave it UNCOVERED!

I have a $10 to $20 fountain that screws into the return instead of the eye that will aerate the water SO quickly that you can raise the pH rather rapidly that way.

This is now really the only acceptable way to raise your pH without causing problems.

It's a component of the process we recommend for lowering Total Alk...you lower pH to 7.0 (where you are) with acid, lowering Tot Alk with it, then raise pH with aeration--Tot Alk doesn't go up. Then you lower pH again with acid and that brings down Tot Alk some more, and you aerate to bring it up.

You are right at the point where aeration is the next step.

Then you'll be fine. BTW, your FC will come down from evaporation, sunlight, kids playing, etc.

Is Arm&Hammer WASHING Soda the same as Baking soda?

Not quite...........washing soda will raise your pH and your TA....baking soda only raises TA.

Not even close!

Baking Soda is safe for human consumption--It's Sodium Bicarbonate and was in use as an antacid for decades. It's used in toothpaste as well. You can even cook with it.

Washing soda is a DEADLY POISON, also called Soda Ash. It's Sodium Carbonate, not BIcarbonate, and gives laundry that really fresh, clean smell.

They are chemically different. One is safe for human consumption, which is why "baking" is in the title, one is not, which is why "washing" is in the title.

Carl, Are you saying that I shouldnt use Soda Ash at all?? My numbers were normal and now they are abnormal again..........

Timmie,
The last numbers you posted were from 17 days ago. We need a current set of numbers to advise you. Also, by the way, FC + CC = TC. Always. Retest and repost and somebody can help you.
