Lime, baking soda, anything alkaline. Above answer is WRONG! Adding alkilies RAISES ph! You need to acidify to lower it. Use Muriatic acid instead. Get it at building supply stores like Home Depot, it'll be cheaper.
To lower pH in Hydroponic gardening
To raise the pH of your pool you add soda ash (sodium carbonate). To lower the pH of your pool add muriatic acid (hydrochloric acid) or sodium bisulfate. You should always add chemicals with the pump running and check your levels again once the newly added chemicals have been circulated around the pool.
Muriatic acid
The pH of a person's blood can tell a lot about their health. Knowing the pH of chemicals can tell how they will react to other chemicals, which can prevent accidents.
The pH gets lower as the acidity increases.
You can but with my experience it will lower your pH,my pH was at 7.8 then i add sand it drops to 7.
Using a pH-meter the measurement is more accurate and sure.

All fish and plants will die. An acid will lower PH in the pond, a level that will clarify will surely kill all living things in it.

Yes, it is common for the company cleaning your pool to also check the ph and help you with any corrections that need done to the chemicals.

No you add acid to lower the pH
