i hozed the test by not testing the water after i added the nitrate, though i did test
before adding and alk was basically unchanged, it seemed to change a tad when there was
nitrate to remove, and not at all when there wasnt its still going and I just tested the
KH its at 10 so its a decrease but its also been running a week with nothing in it once
the stuff i am adding for nitrate desolves completely ill test the kh again see if its
changing the alk

another tank. the
Kh was 11dkh its been going sence 16:00pst ill test again at 21:00pst then
sometime
tomorrow and post all the #'s btw its a large coil and will circulate the
