Hello, everyone! I'm new to this forum and I'm amazed at all the information available here. I've had lots of questions answered by perusing the different topics, but I've not seen a reason as to why aeration causes ph to increase. I just recently converted to a SCG pool, and the water is great, except for a steady increase in ph that I knock down with muratic acid. The aeration I have is from the return jets, and I believe it is caused by some air-sucking joints near the pump. The reason I think this is the source is that when the pump is turned off, water drips out fairly heavily from some of the pipe connections between the Jandy valves and the pump intake. This is from the water draining down from the solar panels up on the roof. Also, my solar panels leak in a few spots. I assume this could also be a source of air inside the system. Any help you can give me will be greatly appreciated! Thanks!
