OK, I've read the articles about how to lower the TA of my inground. First add some acid to lower pH and TA, then aerate to raise pH, then acid, then aerate, and so on. Designing and building a simple PVC aerator that screws into the return doesn't seem so hard. My question is, though, I read the aerators lower the temperature. I don't want to lower the temperature. I don't have a heater and use a solar cover. I live on Long Island, it is August 21, and the temp is about 86. It almost reached 88 one day. I don't want it lower because at this point in the summer I doubt it will raise back up with just the solar cover.
Am I correct that the aerator will lower the temperature?
If so, is there an alternative way to lower the TA?
If I make a short aerator, just above the surface, and point it down, will that keep the temperature from lowering?
