Muriatic Acid: A Popular and Powerful Choice
Muriatic acid, or hydrochloric acid, is a popular choice for cleaning and balancing the pH of pools. It's powerful stuff, so you have to handle it carefully, but when used properly it can work wonders.
Muriatic acid effectively removes built-up mineral deposits and stains in pools. It also helps lower the pH level if the water becomes too alkaline. The ideal pH range for pools is between 7.2 to 7.8. Too high of a pH prevents proper sanitation and the chlorine or bromine from working effectively.
To use muriatic acid, start by testing your pool water to determine the current pH level. Once you know how much you need to lower the pH, calculate the correct amount of acid to add. It's best to start with a smaller amount, say a half gallon, and retest the water in a few hours. You can then add more acid as needed.
When handling the acid, be extremely careful and always follow the directions. Wear proper protective equipment like goggles, gloves, and old clothes. Never add water to acid, always add acid to water. Slowly pour the acid around the edges of the pool, avoiding the filter system and pump. Brush the sides and floor of the pool to distribute the acid evenly.
Retest your pH in 8-12 hours. The pH level should stabilize within a day or two. Muriatic acid provides a fast solution, but for ongoing pH balance, a chemical controller or pH increaser product may provide better long-term regulation. Your pool water should be crystal clear and properly balanced in no time!
Sulfuric Acid: Effective but Potentially Dangerous
Sulfuric acid is highly effective at lowering pH and balancing the water in your pool, but it does come with risks.
Sulfuric acid, also known as muriatic acid, is a strong acid that can significantly lower your pool’s pH and alkalinity levels. When added to pool water, it releases hydrogen ions that neutralize alkaline compounds like calcium carbonate, lowering pH and total alkalinity. Many pool supply stores sell sulfuric acid in liquid or granular form for this purpose.
However, sulfuric acid is extremely corrosive and can cause severe chemical burns, even in diluted form. You must always handle it carefully while wearing proper protective equipment like goggles, gloves, and protective clothing. Never add water to acid, always add acid to water. And never handle or store acid and chlorine together, as mixing the two can produce toxic chlorine gas.
Due to the dangers, some pool owners prefer alternative pH balancers like sodium bisulfate, also known as dry acid. While not quite as effective as sulfuric acid, dry acid is non-corrosive and easier to handle and store. For most pools, dry acid can work great for routine pH balancing and maintenance.
If using sulfuric acid, be very careful and always follow the instructions. Add it to your pool water slowly while circulating the pump, and check your pH levels frequently with test strips to avoid over-lowering the pH. Used properly, sulfuric acid can be a powerful tool for balancing pool water, but safety should always come first. Handle with care!
Hydrochloric Acid: A Balanced, Budget-Friendly Option
A Balanced Option
Hydrochloric acid (HCl) is a balanced choice for cleaning most pools. It’s highly effective at killing algae and bacteria, dissolving buildup, and clarifying water, all while being budget-friendly.
HCl is a strong acid, but when properly diluted to around 1-10% for household use, it’s safe for pools and won’t damage equipment or surfaces. Be sure to follow the directions on the product to determine the right concentration for your pool size and specific needs. At standard dilution, HCl works quickly to lower the pH level and alkalinity of pool water to the ideal range of 7.2 to 7.8, which helps sanitize the water and prevents scale buildup.
Lowers pH and alkalinity levels for balanced, swimmable water
Kills algae, bacteria, and microorganisms that can thrive in pools
Dissolves mineral buildup and debris in pipes, filters, tiles and liners
Affordable, easy to find and use for residential pools
While effective, HCl does have some downsides to be aware of. It can irritate eyes and skin, so wear proper safety gear like goggles, gloves and protective clothing when handling and applying. HCl also produces fumes, so only use it in well-ventilated areas. Rinse any surfaces where acid may have spilled immediately.
For most DIY pool owners looking to balance chemicals and clarify murky water without breaking the bank, hydrochloric acid is a solid choice. With proper handling and dosage, HCl can get your pool clean, clear and swimmable again in no time. Be sure to test pH levels regularly after application to ensure safe and balanced water for you and your fellow swimmers to enjoy all season long.
Phosphoric Acid: A Versatile, Eco-Friendly Alternative
Phosphoric acid is a versatile and eco-friendly chemical for maintaining your pool. It lowers pH and alkalinity levels, providing an acidic environment that prevents algae growth and keeps your water clear.
A Safe, Natural Option
Phosphoric acid is a natural mineral acid found in phosphate rocks. It's non-toxic, odorless, and safe for the environment when used properly in recommended concentrations. Phosphoric acid won't irritate your eyes or skin like muriatic acid and releases fewer harsh fumes. This makes it a good choice if you have children or pets around your pool.
Lowers pH and Alkalinity
The ideal pH range for a pool is between 7.2 to 7.8. If your pool water tests above 8, phosphoric acid can lower the pH to the proper level. It also reduces total alkalinity, which measures the ability of the water to resist changes in pH. Lowering alkalinity makes it easier to adjust and balance the pH.
Add phosphoric acid a little at a time, then retest the water in 4 to 6 hours.
For every 0.2 increase needed to lower pH, add about 1 gallon of phosphoric acid for every 10,000 gallons of pool water.
To decrease alkalinity by 10 ppm, add around 1/2 gallon of phosphoric acid for every 10,000 gallons of water.
Prevents Scale and Staining
Phosphoric acid helps prevent scale, stains and mineral buildup in your pool. By controlling pH and alkalinity, phosphoric acid creates an environment where it's difficult for scale and stains to form. It can also help remove existing scale and stains when used at proper levels.
Using phosphoric acid to maintain your pool water is an eco-friendly way to keep your pool clean, clear and balanced all season long. Be sure to follow the directions and test your chemical levels regularly to achieve the perfect balance.
Citric Acid: A Natural, Non-Toxic Choice for Sensitive Pools
Citric acid is a natural, organic acid that’s perfect for sensitive pools or those concerned about harsh chemicals. It’s non-toxic, eco-friendly, and gentle enough for vinyl liners and swimsuits, all while effectively balancing your pool’s pH and alkalinity.
