    Running Liquidator with FC levels lower than chart

    In this thread duraleigh described an innovative experiment with the Liquidator. Although his CYA level was 60, he ran his LQ for 8 weeks at pool FC level of 1-2 ppm. The only reason he got an algae bloom was that he wasn't careful to prevent the FC level from dropping further down.
    To the best of my memory, no one else has ever tried it.
    Although the theory is important and still unknown, the facts and the practical aspects are more important.
    The purpose of this poll is to examine if the Liquidator can be safely run with FC levels lower than the FC/CYA chart.
    LQ owners: Please respond to this poll.
    This is my ticket for Heaven (when all's working..) :
    22k Gal gunite IGP, 38 SF Anthony DE filter, 1 HP Hayward Super Pump
    380k BTU Raypak Natural Gas Heater (Model RP405A) and solar cover
    8 gal Liquidator w/ 12% bleach, Dolphin Diagnostic Advantage robotic cleaner. 3800 ppm salt, 50 ppm borates.

    Re: Running Liquidator with FC levels lower than chart

    You are forgetting some other important variables such as bather load and sunlight exposure that will have an impact on the results of this poll. There is much documentation that those that use peristaltic pumps cannot get away with lower FC levels and that the lower levels that seem to work with a SWG have a lot to do with the extremely high concentraton of chlorine that is in the cell and pipes as the water is introduced back into the pool.

    Re: Running Liquidator with FC levels lower than chart

    I was running mine 1-2 ppm lower for the last 2 months of the year.In the vote I said I got algae but I truly didn't have a full blown bloom, But I was starting to get cloudy water and I think I was headed that way. Ive never had algae when I keep it at chart values.

    Re: Running Liquidator with FC levels lower than chart

    Obviously we can't control and compare all the variables but at least we have one common denominator: use of a Liquidator. No Cl pumps, no SWG.
    Duraleigh did something not "by the book" and the question is: can we do it too.
    As far as sunlight intensity is concerned: If duraleigh could have done it in NC, where the sun is at a higher angle than in my area, and if sun light intensity is an important factor, then I can do it too.

    How did you fix the cloudy water issue? Did you check for CC? Did you shock? Or did you simply go back to the chart FC value?
