A small of amount of muriatic acid
To raise alkalinity in a spa using borax, you can add 1/2 pound of borax per 500 gallons of water. Start by adding this amount, then retest your water after a few hours to check if the alkalinity has reached the desired level. Adjust as needed based on your test results.
lower it
pH refers to the level of acidity or alkalinity. less than 7 is acidic, more than 7 is alkaline. if you want to lower your alkalinity, add muriatic acid. It will lower the pH though
Yes it does. Some pool management systems use CO2 to lower the pH of the water. Of course if it is used regularly the Alkalinity will soon fall. Michael
Initially, you can't. What you do to lower alkalinity is first lower the pH to under 7.2, but not lower than 6.9. Then you aerate the pool, by creating bubbles with your brush, or by running a water feature, if you have one. This will lower your alkalinity. Maintain this lower pH and aerating until you get your alkalinity where you want it. Then retest your pH. If it is now too low, you add Mule Team Borax, say a 1/4 a cup, and then retest. The borax will raise your pH without raising your alkalinity. See the poolforum.com for more help if needed.
No
To lower alkalinity in well water, you can try installing an acid injection system to neutralize the alkalinity. Another option is to use a water softener with an acid regeneration option to reduce alkalinity levels. It's advisable to consult with a water treatment professional to determine the best solution for your specific well water.
Add rain water this has very low alkalinity
baking soda
It is used to lower both ph and alkalinity.
To adjust pH and/or lower alkalinity.
If the vinegar is more acidic than the liquid you're adding it to, yes. If you're adding vinegar to a liquid already more acidic, the opposite will happen.
