Adding Acid To Vinyl Pool

Muriatic acid is commonly used but also dry acid.

Adding acid to vinyl pool.

If you are adjusting the ph in a vinyl lined pool using muriatic acid add slowly to the deepest part of the pool with the pump on and water circulating. Measure the dry chemical pre dissolve in a bucket and pour around the perimeter of the pool never into the skimmer directly. If you need to bring your ph back up a little you can continue running your pump to aerate the water. The effect of muriatic acid on pool surfaces however is hard fact.

Muriatic acid and chlorine are the main chemicals. What follows is to add the mixed acid to the pool water. Turn on the pool pump and slowly add the acid and water mixture all the way around the pool s perimeter. Muriatic acid contains hydrochloric acid concentration levels between 28 to 35 percent.

Do not re enter the pool for at least half an hour. Be aware that because cya is an acid it can cause damage to your filter and to your pool especially if you have a vinyl liner. If the ph levels are still too high you may add a little more muriatic acid. Always add acid to water never water.

Make sure to turn on the pool filter before adding the acid. Even though some cyanuric acid product labels may instruct you to add it by pouring it straight into the pool or filter don t. This will not harm the vinyl liner although unbalanced chemicals over time will have damaging effects. Even diluted muriatic acid can potentially cause harm.

When it comes to adding make sure to do it in small portions and not to stick to one area of the pool. This dilutes it a bit. Check the ph levels again. After a few hours test the ph level again.

If you want to be sure you won t accidentally damage your pool turn your pump back on for half an hour immediately after adding the muriatic acid. The return jets in the pool help with spreading the acid evenly in the water. Yes you should take some extra precautions when adding some chemicals to a pool with a vinyl liner.
