“Carbonates” Support pH, But Can Be Exhausted

Carbonate balance is a long subject, but I intend to keep it brief. I will over simplify for greater understanding. As we mentioned before, pH is a measurement of Hydrogen ions in the system. Hydrogen ions can come from the reduction of Ammonia and several other biological processes. We mentioned that in the absence of carbonate molecules, these Hydrogen ions would drive down the pH.

“Carbonates” Support pH

Carbonate molecules come from several places. Sometimes, they occur naturally as a result of the dissolution of rocks like Limestone and Dolomite. These rocks are made of Calcium and Magnesium carbonate. When these rocks dissolve they release those minerals, plus Carbonates.

Unnaturally, the carbonates may be supplied directly in the form of Sodium bicarbonate. Indeed this is nothing more than Baking Soda. (pH Pills Home Made)

Carbonates can be supported by pH PILLS
Carbonate in the water to support pH can come from pH Pills.

The carbonate molecule exists in a balance with the environment. When Hydrogen ions become abundant, the carbonate molecules pick up the extras, which prevents the pH from falling. When hydrogen ions become scarce, as in a high pH [to assign a number; 8.3] the carbonate molecules will liberate some Hydrogen ions.

“Carbonates” Support pH

The net effect of the carbonate molecules on the water is to hold the pH at some, constant level. This is why there is a benefit in knowing the “number” [quantitative] measurement of carbonate activity.

Carbonates And Bicarbonates
Most biological processes produce carbon dioxide, which becomes carbonic acid, which brings down the PH.

When you’re measuring the carbonate levels in a system, it’s known as a test of the “Total Alkalinity” of the system. There are affordable Total Alkalinity test strips on Amazon, at most major garden centers and pet shops. Pools supply stores also provide very reliable strips that measure TA.
