I'm converting my neglected pool over to BBB and was wondering if I should still use the auto chlorinator with the pucks? Also I'm using a basic 4 test water test kit but the numbers do not appear to correlate with the standard PPM numbers needed to use the Pool Calc to figure out how much bleach is needed to reach shock level. Is there a way to convert the numbers on this test kit (0.2 - 5.0) over to actual PPM until my TF-100 arrives? Can I get accurate PPM numbers from the kid at "Steal-A-Penny"? Thanks!
