How Much Muriatic Acid To Add To Pool? (Secret Revealed)

So, you’re ready to add muriatic acid to your swimming pool. But, how much acid do you need?

Well, the amount needed will depend on a couple of different factors, like the size of your pool, the volume of your water, and the pH balancing system you have.

In this article, I’m going to tell you what type of system you have and how much Muriatic Acid you need to add to reach a certain and normal pH level.

How Much Muriatic Acid To Add To Pool: A Detailed Guide

Below are some known measurements of Muriatic Acid you can add to stabilize the pH level of the pool.

How Much Muriatic Acid To Lower pH In Pool:

A rule of thumb says that you should add 1 gallon of muriatic acid per 10,000 gallons of pool water. It will lower the pH by about 0.5 points and raise the TA by about 0.5 points (if you do it slowly).

Pour a gallon down each skimmer vacuum port to get this much acid in your pool. This will also help lower the TA, but again only by about 0.5 points at most.

It is often more practical for larger pools to simply increase your chlorine dosage to compensate for the acid being added to the pool water. As a result, your chlorine level will go up, but not enough to cause problems with eye-stinging or irritation of skin or mucous membranes.

How Much Muriatic Acid To Add To Pool With Algaecide:

Muriatic acid is a strong acid that is used for cleaning and etching concrete surfaces, and it is also used to remove algae from swimming pools. The amount of muriatic acid that you will need to use depends on the size of your pool and the type of algae that you are trying to kill.

You can use this formula to calculate how much muriatic acid you will need when adding it to your swimming pool:

1 quart per 10,000 gallons of water = 1 lb per 1,000 gallons = 3 oz per 300 gallons = 2 pints per 600 gallons = 1 pint per 800 gallons = 1/2 pint per 1,200 gallons = 1/4 pint per 2,400 gallons = 1/8 pint per 4,800 gallons

How Often Do I Use Muriatic Acid In My Pool

The answer to this question depends on several factors like the type of pool, what type of chemicals are being used, the pH level, and other factors.

In general, if you have a chemical-free pool, you can use muriatic acid once every two weeks. If you have a chlorine-based pool, you may have to use it more often.

The pH level of your tap water is also an important factor. The pH level must be below 7 to be effective as an algaecide. If the pH level is above 7 then it will not work as an algaecide or stain remover since it will not be able to break down the cell walls of algae cells or stain cells.
