My last post to this thread: I believe I have got it covered for now.
My tank is a 72 gal
bowfront with 20 gal
sump. I would estimate with rock and sand I actually have about 75 gal
max, maybe 70. For the last week I have ran kalk
made with pickeling lime at 1 teaspoon per gal
. Over a 4 days my Kh
dropped 1.7 dkh
. My ph ranges between 7.83 and 8.01. I would prefer it be closer to 8.2 ph. I understand the kalk
should help that also.
I would then expect a daily drop of .425 in kh
daily if my math is correct. I also understand pickeling lime is slightly less potent than the kalk
I got from BRS according to them anyways but IMO
CH is Ch. I also now know I jumped into the kalk
sooner than really understanding it as I should and errored on the light side of the mix.
I think that all means using the BRS calculator I need a daily dose of 0.26 gal
of fully saturated kalk
water daily to maintain current level. I go through about 0.50 gal
of top off daily on average. Since I am dropping kh
with 1 tsp of kalk
would it make since to go to 1.5 tsp per gal
in my ATO and keep an eye on it and see were it all settles out at?
I also have my RKL alarm set to 8.35 ph to override the ATO and shut it down if it gets out of hand.
