An acid wash is the most effective way to deal with the problem of harmful algae, but if you do it too often, you will end up paying for a pool replacement. Acid washing will literally remove a thin layer of plaster, allowing you to start over. With most layers of pool plaster about 1.25 centimeters (1.2 inches) thick to begin with, acid washing should be reserved for occasional maintenance.
When Should You Acid Wash Your Pool
Acid washing is done for one of two reasons. The first reason is that the algae can be removed. When you can’t see the bottom of the pool, or if algae is a persistent problem every year, it’s time to use acid to clean the pool. If you are just starting to see algae bloom, you can attack the problem with a less dangerous and cheaper detergent.
Some people choose acid wash to give the pool a pearly white finish. If you don’t have algae problems or haven’t done the acid wash in many years, that’s fine. Don’t acid wash scratched vinyl pools – you’ll likely have to pay for an expensive repair to replace the finish.
How To Prepair Your Pool For An Acid Wash
Before washing your pool with acid, empty it and clean it. Contact your local water and sewer provider to let them know that you are emptying your pool. The municipality can file charges if you don’t notify them in time. If you hire a pool cleaner to do the acid washing, it will come at a cost, but doing it yourself will save you money.
The process is very time-consuming, but it is simple. It cleans and scrubs algae, leaves, and other debris from the pool walls as it empties, and then removes any debris that has collected at the bottom.
How To Acid Wash A Pool
It is highly recommended to hire a specialist to do the acid wash. Acid is a dangerous substance that can hurt you, the pool, or the environment, if not used correctly. If you decide to do the process yourself, be sure to work as a team in case of accidents and put on all the appropriate safety equipment, including rubber boots, gloves, a breathing apparatus that will block muriatic acid vapors, goggles, and clothing. that covers your arms and legs.
Mix 1 gallon (4.3 liters) of water with 1 gallon (4.3 liters) of muriatic acid by pouring the acid into the water in a watering can. Never pour the water into the acid. Wet the surface of the plaster with a hose. Let the water in the hose run for quick access during the process. After wetting the surface, work in 10-square-foot (0.9-meter) sections, pouring the acid solution down one side. Allow the acid to settle for approximately 30 seconds, then scrub with an acid brush before rinsing it off. Rinse well.
After the entire pool has been acid washed, neutralize the foamy acid puddle at the bottom by adding 2 pounds (4.4 kilograms) of soda ash for every 1 gallon (4.5 liters) of acid used in washing. Stir with a long-pole pool brush, then pump the water out with a small submersible pump. Be careful where you pump the water from. Even though it has been neutralized, it can still harm some plants or animals. Rinse the container in the deep end as well.
