Thank you for the reply and happy holidays!!!! I dosed my 120 gal with B-ionic 2 part with
20ml, equal amounts. My Cal went down 370 to 365 and the Alk up 7.0 to 8.6

Is that normal to get such a jump on Alk and can I dose a little extra of the cal until I am at 450 then dose equal amounts.

Thanks again

Randy's on vacation, so you're stuck with me.

Dosing just the calcium part is fine. I do the same sort of thing with B-Ionic from time to time. I'm a little worried that calcium went down, but the numbers are close enough that a little testing error would explain them, so I wouldn't worry just yet.

It's fine to use the two part's independently if need be. But I'd still question those test reading's. I feel with this weekly testing is better because the kit's are not accurate enough for daily changes unless your drastically underdosing. 20 ml is a small dose for that size tank and shouldn't change the values much at all. For the alkalinity, that dose will raise your level no more than a tenth of a meq/l

Thank you both. My readings have been steady at Cal 385 and alk 8.5 slightly dropping. Welcome to the big times. i now realize that a 120 takes ALOT bigger dose then I thought!!!
I have been dosing 40ml even and holding the above numbers. If I dose more ALK when and do
I dose even parts again? Thank You.

Forgot, at first used Alk test kit wrong. It comes with a 5ml syringe but you only use 4ml of H2o.....

Personally, I would dose alkalinity to 10 dKH and calcium to 400-450 ppm, and then start using equal amounts. This calculator migth be useful:

Just up the dose of both part's a bit untill you maintain the alkalinity level you wan't. You won't have to worry about calcium as much. Dosing in the morning is best for the alkalinity part. Just wait at least a few minutes to add the calcium.
