It's getting hot in Phoenix and the pool is now uncomfortable. Water temp is at 90*. I'm a new pool owner and am not sure the best way to go about trying to lower the water temp a few degrees.
I tested pH, Chlorine and TA this morning. The other tests are from last weekend. Over repeated tests I have had no CC so I did not include that.
TC - 3
CYA - 60 or 70, right between the two (I tested twice!)
TA - 80
CH - 380
pH - 7.4
I was running my pump for six hours in the late evening/early morning but I think I am going to split that into three hours in the late evening and three hours in the late morning. I haven't had any issues with algae or cloudiness at all. I do have to add ~1/2 gallon of MA each week to keep the pH in check. My chlorine levels have been dropping a bit so I'm also going to increase the SWG 10%. CH has also increased from 300 to 380 in just a couple of months which is starting to concern me. I drained and filled the pool in late March but didn't have a CH test kit until the beginning of May.
Onto aeration - my pool is basically a rectangle, with an aerator spout on the long side (meaning it blows a fan of water across the shorter distance at roughly a 40* angle). It is controlled by a manual diverter valve. Wide open it can blow water across the entire pool with a small amount landing on the cement decking. I have an in-floor cleaning system so the amount of water tossed by the aerator varies based on the current location of the water being pumped.
What concerns should I have in running my aerator, especially regarding the fact I already have to watch the pH very closely? Is it going to get completely out of control with me tossing water into the air?
Is it OK if I blow a little water out of the pool, or is that a bad idea for concern of the concrete decking considering it's 110 degrees here? A little part of me thinks it might help my CH numbers, but I doubt enough water will get blown out to impact it. And there's probably 10 other things wrong with that thought.
Anything else I should be concerned with or think about? Any other recommendations on just about anything? As a pool noob I'm open to all suggestions.
