I can't let it go on for that long making that kind of noise--sounds much like a jet aircraft in the backyard! It's only a matter of time before my elderly neighbor, who doesn't like us anyway, starts complaining since it's on her side of our back yard. I was noticing this morning while I was at the barn feeding the horses that I could actually hear the pump over there--at least 2 acres away! I just hope I can get this algae bloom cleared up before it gives up and dies. Algae is dead, just filtering out the dead stuff, but still have a ways to go.


On a side note, normally when I have algae that I'm killing off, I never have CC....this time, the CC actually hit 4 ppm today during sunlight, but was down to 2 this evening when I added the next bleach dose. Ambient air temps were in the mid 60s today but the water is still pretty cold....wondering if cold water makes the CC more resistant to dissolution by the sun than warm water, or if some of my CYA has gone away and this is just the residual chlorine demand? Water is too milky to test for CYA right now but it'll be interesting to see if it lowered any.
