    Pump timers and dirt

    I have my pump on a timer, and right now it's running about 6 hours per day. (I haven't even tried to calculate how long it really needs to run to do a complete turnover.) The water is crystal clear, but I'm getting a lot of dirt build up on the bottom. My chlorine demand is under 0.5/day if I keep the solar cover on, and my CCs are always < 0.5, so I'm sure it's not algae. In addition, there is a lot of dust building up on the solar cover too.

    This must be a normal trade-off - if the pump isn't running, the water isn't getting filtered, so anything that gets into the pool will settle to the bottom, and then you have gunk. I could run the pump more, thus getting less gunk, but where's the sweet-spot between power consumption and dirt?

    So how do you deal with it? Just vacuum more often? Ignore it? What?

    I don't have a two speed pump, and it's not really cost effective to replace my working pump with a new one.

    Before I speak, I have something important to say.

    In the spring, when the pollen is really coming down, I run the pool cleaner much more often than I run it during the summer. With manual vacuuming it is the same thing, more frequent vacuuming.
