Muratic, Bleach, Borax and Baking Soda (and Muriatic Acid)

Muratic - Lowers pH
Borax - Raises pH
Baking Soda - Raises Alkalinity
Bleach - Liquid Chlorine - Sodium hypochlorite

You will also need conditioner since you are no longer getting it with the chlorine products...

www.poolcalculator.com is suppose to be the place to go, but you have to download and app and give up your search engine prefs to use it? wtf is that...

CYA Problems

Too high and the only thing to do with confidence is drain pool and add water to dilute. Chemicals exist but they may cause a mess...

BBB you deal with pH and Chlorine and others are secondary.. (CYA

Ideal pH - 7.2 to 7.6

Muratic to Lower - Acid Demand Tables or...

Borax to Raise - 0.5 teaspoons per 26 gallons. to raise it ?? https://thepoolarea.com/bbb-pool-method/
Baking Soda - .5 teaspoons per 26 gallons to raise it ?? https://thepoolarea.com/bbb-pool-method/
Bleach - 2 teaspons per 26 gallons to raise it ?? https://thepoolarea.com/bbb-pool-method/

Calcium to be monitored in concrete pools...

Hi levels of these can not be fixed easily with chemicals. The pool must be drained to water down the problem.

CYA ideal is 30-50ppm

Calcium Harness ideal is 200-400ppm for pools and 150-250ppm for spas

Hi alkalinity (may be due to hi calcium):

1. Irritates swimmers - burning eyes, itchy skin, degrades clothes and fabric prematurely

2. Reduces effectiveness of chlorine - just the nature of the chemistry

3. Creates cloudy pool - typiclaly b/c of calcium present

4. pH will be too high - lower pH can be done but it's harder with hi Alkalinity

5. Scaling can occur - Calcium deposits and damaged pool equipment and filtration systems

Muratic Acid - pH between 1 and 2

• Turn OFF pump

• Use digital test kit or strips to determine alkalinity (what about water kit?)

• Typically, 25.6 oz of full strength acid to lower 10k gallons by 10ppm

• Can dilute the acide 10:1 in water prior to adding to pool to make is safer for pool walls and such

• Pour into deep end and let sit there for 1 hr

• Turn pump back on and retest for alkalinity and pH

Dry Acid - Sodium Bisulfate

• Safer but more expensive than muratic

• Store in dry place

• Measure like above

• Fill bucket 3/4 water and add acid

• Mix using wooden stir stick until acid dissolved. Undissolved will sink to bottom and eat pool

• Carefully pour around perimeter starting at deep end

• Retest
  
  NOTE: doesn't say anyhing about the pump thing with liquid acide

To bring pH back up...

• Baking Soda (sodium bicarbonate)

• Soda ash (raises Alkalinity more)

• Aeration - adding oxygen
  NOTE they don't mention Borax at all... which is the BBB method... Seems like an add for aerators...
