Alk / Calcium problems

I am having some problems maintaining calcium and alkalinity.

Lately I have been testing several times a night, in batches of 3. Three in
regular res mode, by following the posted directions. And three in what I
call super-res, by doubling the components.

Calcium won't go over 375 ppm (confirmed with 2 seperate test kits both with
standards) But it is constant there. Doesn't change from day to day. (even
running the tests in super sensitivity mode.)

Alk runs high from 3.2 to 5.2 meq/L.

I dose with 2 part B-Ionic and/or Kalkwasser. When I use the 2 part, alot of
times I end up just dosing part 2 (calcium component) so not to over-do the
alk. When I am dosing Kalk, I set it up on a drip, totals about 1 gallon per
day. (Which just so happens to be about what i loose in evap) I make the
Kalk up in 2 gallon batches.

When I dose B-Ionic I end up dosing about 50 ml of part two in a 46 gallon
bowfront. This amount seems enough to maintain the calc, but not raise it.

I would like to get calc to 400 to 425. Any advice?
Also, I would like to get the Alk down. Not dosing for a while works but I
was wondering if there is a method that can be used to raise it, besides
water changes. (do enough of them @ 20% each month)

Best regards,

Rick
