Help With KH

[Myka]

Oh I know you're not new to it, but why do you want numbers that high? Do you have a reason? At least you are bumping up your calcium to match the elevated alkalinity you want to keep. That's a good step. Seeing as you want to keep the alkalinity that high, you may as well keep the calcium and kalk reactors online right now to hold the 10 dKH alkalinity level you are at, and just manually add extra calcium to get it up to the 440 ppm you want it at.

Basically, all you need to do is manually dose the tank until the numbers are balanced on that chart I posted. It doesn't matter where on the chart they are as long as they are balanced, then turn the kalk reactor up or down a bit (it's easier to fiddle with than the calcium reactor) to raise or lower your now balanced numbers to the ones you want. Get it? If not, you can send me your phone number and I will try to explain better that way.

But no, you can't raise calcium without raising alkalinity with either of your reactors. You have to manually dose whichever number is low, in your case calcium. You shouldn't have to manually dose very often when you have reactors (say once every 2-4 weeks), but you will have to. No reason to take them offline...
