Muriatic acid and swimming pool chemistry. No problems lowering levels with inground pool maintenance, salt water pool maintenance and above ground pools.
It is one one of the most corrosive forms of acid and its use goes from swimming pool care to metal and brick cleaning.
If you happen to spill some on your clothes, fabrics, varnished furniture, plastics, or most any painted surface, you can say bye-bye to them because it will eat through these things before you're able to wash it off.
Great care must be taken to ensure you're safe around this kind of acid.
There are mainly two kinds that you need to be concerned about. They are:
Dry acid is easier to store, handle, and apply but also must be used with care.
The two main uses for hydrochloric acid is to lower your pool pH and pool alkalinity levels.
The process on how to do that is found in the above links and also in the charts below.

Once again, be aware that muriatic acid is dangerous so take the proper precautions when making any adjustments to your pool and handle it with care.
