    So you want to add borates to your pool--Why and How

    *Sorry*, I just realized that the 50 mg/liter mentioned by the EPA test was boric acid. The state that 17.5mg/liter of *Boron* was enough to cause 50% mortality. So if this is the case, 50ppm in the pool is definitely greater than the 17.5ppm required to kill 50% of the bees tested.. Assuming...

    So you want to add borates to your pool--Why and How

    Yah, I was a bit confused regarding their ppm to mg/m^3 conversion. If 50ppm equals 50mg/L then according to that EPA test, there would be no effect on bee mortality until the level raised to 100ppm (100mg/L) and that assumes the bees intake as much pool water as syrup/nectar. The EPA mixed it...

    So you want to add borates to your pool--Why and How

    Thanks for the fast response! I did find this mentioning in the Boron EPA study that was posted in this thread: And at the top: If I did my math right: the 8.7mg boron/liter that was still 'ok' for honey bees comes out to: 8.7mg/L = 8700mg/m^3 * 1ppm / ( 0.4421mg/m^3 ) = 19,678ppm Assuming...

    So you want to add borates to your pool--Why and How

    Thanks for all the great information about adding borates! I was wondering two things: 1. Does adding borates cause any clogging issues with DE filters (or DE filters using FiberClear)? 2. We keep honey bees, and I was wondering if anyone knew of any problems as apparently it kills insects...
