Does Rain lower pH in pool?

Rainfall dilutes pool chemistry levels and lowers the readings for pH, alkalinity, hardness, stabilizer, and chlorine. Rainfall does not contain chlorine. As well, rainfall brings with it small amounts of contaminants that are washed into the pool.

Can you use vinegar to lower pH in pool?

Lowering pH with Vinegar Commercially distilled white vinegar, often 5 percent acetic acid, has a pH of 2.4 and can be used to lower the pH in salt water aquariums. This amount should lower the tank pH by about 0.3 points. … Most pool experts recommend a pool pH between 7.2 and 7.8.

Why is my pool still green after shock and algaecide?

If you do receive a higher reading this simply means your water is alkaline and may potentially turn cloudier than normal after the chemically shocking your pool. You simply need to introduce hydrochloric acid to the water as this acid neutralises basic elements. Don’t worry if you’ve accidentally added too much.

Does chlorine make pH go up or down?
