    Liquidator & Variable Speed Pumps

    What is the preferred / easiest method of setting this site? Just have say an hour cycle on high RPM to dispense the chlorine?

    Re: Liquidator & Variable Speed Pumps

    I was also looking into the Liquidator and have a VS pump. From what I understand, this is one of the disadvantages of the Liquidator compared to a Stenner. Since, the Liquidator will always be dispensing when the pump is running, you will get variable amounts of chlorine depending on the RPM of the pump....making it hard to tweak the settings. I run a low RPM for filtering and a higher RPM when the Polaris is running so I think I will run into this problem.

    Re: Liquidator & Variable Speed Pumps

    A Liquidator and a variable speed pump is not a good combination. One hour on a fairly high speed is not likely to be long enough to feed a sufficient amount of chlorine, and longer high speed run times kind of defeat the whole point in having a variable speed pump.
