I read a post recently about people lowering there ph and then raising it up with aerating. Forgive me because I know I am missing an important part of the chemistry. anyway, I watched a youtube video yesterday that sparked an idea. It was a person showing how a wrongly placed O-ring was making bubbles get pulled into the pump. not enough to starve the pump by any means, but I got to thinking... All the posts I read regarding the above mentioned ph fix, people tried pressure washers, propping the pipe to shoot out of the pool and back in, and even a cement filled pvc pipe hooked to an air compressor. Couldn't you just loosen one of the unions on the suction side of the pump just enough to where it was pulling air in due to a loose connection?? I am sure you could rig it up somehow so this scenario would work and in my opinion, with a pump the size of mine (1 horsepower) that would push a ton of air in the water over time.
