    Backswimmers, Argh. Oh, and Hi!

    New here, I've been lurking since I started researching pool maintenance in September of 2011 when we purchased our house with a pool. Glad I've avoided the pitfalls of the pool store advice and have been on the BBB method this year. It's so easy, and my kids think I'm a scientist with my Taylor test kit.

    First and formost my current levels

    FC 10 <- I lose about .5ppm overnight and about 3ppm during the day with cover off
    PH 7.4
    TA 100
    CH 275
    CYA 40

    Putting the cover on the pool for the night I noticed a backswimmer, by the time I ran to get the skimmer it was long gone. I hate bugs in pools, and this has been vexing me since. I've already done a little searching around here but wanted to see if anyone has a link between cover off time / heat and the presence of these annoying creatures. My FC has been well near the top end of the recommended FC for my CYA, actually a little above since we have a lot of bather load with these hot days.

    We've been having 95?F (35?C) days for a couple weeks which is great for swimming (not for landscapes though) and I've started keeping cover off to keep the water temp under control.

    Are these pests just a fact of pool life? Anything I can do to discourage them? Is the cover off all day encouraging them to jump in?

    Welcome to TFP

    You can try borates - that tends to keep most insects away.

    Welcome,

    I used to get backswimmers all the time, until I started the BBB method. I noticed you are doing BBB too, but really had to keep on top of the pool everyday to keep them out. I noticed if I keep my PH around 7.6 and FC levels around 9-10 I never have a problem. The minute I let the FC go down below 4.0, I started seeing them again . I decided, every night, just to raise up the FC and keep it near the max 9-10ppm. Since I've been doing that, I never see them. Hope this helps

    I don't see backswimmers anymore with my clear water but I still get bees. flies and wasps. I do have a little borate (about 15 ppm) but nothing has kept the bees out.

    Ran at 10ppm for another week with no more signs of them, trying 8ppm now to see how it goes.
    Thanks!

    BTW, I have heard that the borate test strips are on back order and have been temporarily removed from the web page. Keep checking this link to see when they become available: http://tftestkits.net/Single-Item-Tests-c6/
