    Hawkeye's Baq Conversion

    i tested last night for overnight fc test, i got the fc level up to 16.ppm last night and this morning it dropped to 14ppm and cc was 0.4 ppm it only takes like 3 drops to get cc to change back over clear again does this sound right? and that 0871 reagent i use like 70 to 85 drops to test around this higher range?... so i am totally getting used to my new taylor 2006 test kit i like it alot but i had to get a 2oz bottle of 0871 any info would help thanks mike b

    Re: my coversion is almost complete!

    Something doesn't sound right....

    What size water sample? With 10 ml sample, If the FC was 16, it would mean 32 drops. If you did 3 drops for the CC, your CC is 1.5.

    Re: my coversion is almost complete!

    It sounds like you are doing well. With only a 2 ppm drop in FC overnight you are nearing the end of the conversion. Keep at it for another few days and you will be there.

    Doing the FC/CC test with the 10 ml sample size is less precise, but it is fine for what you are doing right now. For that matter, it is fine for nearly everything. There isn't much point in doing the test by 0.2s, when measuring FC levels up around 15, it takes extra time and uses up reagent.

    You don't want there to be any CYA in the water until the next to last step in the conversion. You are almost ready to add CYA, but not quite yet.

    When the FC holds overnight, you change out the sand.

    Then you add CYA to a sock, and set the sock in the skimmer, don't block the water flow, or tie it off in front of the return - wherever it will dissolve faster. Keep the pump running while the CYA dissolves. Wait a week before you test for it again, or you'll just waste reagent.

    Shock again until the CC is .5 or less for two consecutive nights, then your conversion is complete.

    Re: my coversion is almost complete!

    When making a big chemical change, I typically use 2/3 of the recommended amount initially, then follow up with whatever is needed on a second dosing.

    You want to maintain the FC at 15 until you have CC at 0.5 or lower on two consecutive days.
