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..


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.
