When adding acid it s best to mix it first in a bucket with water.
Adding acid to vinyl pool.
Adding muriatic acid directly to your pool can create a hot spot of acid that can potentially burn or irritate the skin if you swim too early.
Acid is heavier than water and will sink straight to the bottom.
Muriatic acid and chlorine are the main chemicals.
Yes you should take some extra precautions when adding some chemicals to a pool with a vinyl liner.
Add the 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.
The return jets in the pool help with spreading the acid evenly in the water.
Do not re enter the pool for at least half an hour.
This will not harm the vinyl liner although unbalanced chemicals over time will have damaging effects.
What follows is to add the mixed acid to the pool water.
This dilutes it a bit.
If the ph levels are still too high you may add a little more muriatic acid.
If you need to bring your ph back up a little you can continue running your pump to aerate the water.
Check the ph levels again.
Always add acid to water never water.
Muriatic acid is commonly used but also dry acid.
When it comes to adding make sure to do it in small portions and not to stick to one area of the pool.
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.
Even diluted muriatic acid can potentially cause harm.
Make sure to turn on the pool filter before adding the acid.
Measure the dry chemical pre dissolve in a bucket and pour around the perimeter of the pool never into the skimmer directly.
The effect of muriatic acid on pool surfaces however is hard fact.
After a few hours test the ph level again.
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.
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.
