How Many Aerators do You Need

The aerator is powered by water pressure, so a good pressure will produce a higher amount of bubbles, a lower one less or not at all.

If one of the pool nozzles doesn't have an aerator installed, the water will drain through it more easily, and the nozzle with an aerator installed in it, will get insufficient pressure. So, you need to install an aerator in each nozzle of the pool or, the nozzles without aerator to be reduced/closed with plugs.

Also, check the filter to be clean, also for a normal pressure!

Aeration reise pH without chenging alakalinity

Over-aeration can raise your pH levels beyond the recommended range. 

Be sure to test your pH and total alkalinity regularly. Your pH should be between 7.4 and 7.6 and your total alkalinity should be between 100 and 150 parts per million (ppm)

If your pH has risen dramatically, you need to remove the air pipes, and the aerators will become simple nozzles
