How do you bring alkalinity down?

Answer 1

To lower the alkalinity in a pool you can use PH Minus or Muriatic acid. When adding pour into one spot in the deep end of the pool away from circulation, make sure the circulation system is running. Do not apply near metal fittings or near the pool skimmer. Also make sure you follow directions when using the product.


To lower alkalinity in an aquarium, you can use peat moss in the filtration system which will not only lower the PH, but help with stability

Answer 2

To lower the soil pH, add more acid to it by adding 1.2 oz. of ground rock sulfur (another readily available sample) for every square yard of soil in gritty soil conditions, or add 3.6 oz. if your soil is more clay based.

Answer 3

Short answer is you can't. Long answer is lowering ALK is a process. You add acid which drops pH and converts bicarbonate (which is the main component of ALK) to carbonic acid (basically carbon dioxide dissolved in water). You then wait for the CO2 to gas off (aeration speeds this up) and whenit does pH rises since you have decreased the amount of carbonic ACID (operative word is ACID) in the water. If Alk is not low enough the processis repeated. It is never a good ides to drop the pH below about 7.0 each time you add acid to lower the pH for various reason so this process can take several day or longer to complete (depending on how much you have to reduce the ALK and the amount of aeration you are able to provide to speed up the outgassing.

The old adage that "walking acid lowers pH and pooling acid with the pump off lowers ALK" is simply not true and has been scientifically disproven, not to mention potentially harmful!
