I have been fighting cloudy water for the past two weeks and am finally making progress by following the BBB method and a ton of patience. I also employed the DE trick to my sand filter. I haven't been around in a few years; due to Ben's excellent training, I haven't had many issues. I am however curious about the cost (ball park) of running a 3/4 HP pump 24/7, which is often recommended on this site to clear cloudy water. No other issues, just wondering if anyone has tracked this. Thanks, Guppy.
