DIY Coil Denitrator Questions

ok 10dkh so a small change but no change with the addition nitrates enough for 200ppm

it would seem to consume them a little (remember 10gallon), but only when its consuming
nitrates. this 10 isnt a cycled tank, it has no source of ammonia/nitrite/nitrate besides
what I added to it. so scaling that up to something usefull with a nitrate source it
probibly does consume alk, and you might expect it to stop as soon as you get to a lower
level in your tank..

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

..... but just to be certain ill test the Kh of a quasi control tank a
10gallon with
nitrate levels of 200ppm i put an already established coil onto it from
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
tank water in
aprox 2 hours. I might check it then just to see what the #'s come out as,
but wont post
them at that time.

Any results Richard?

That makes sense with what I have seen - as my Nitrate levels in the tank
have fallen so the effect on the Kh seems to be less dramatic.
Thanks for doing that - something else learned.
