I have been adding sodium bicarbonate.

I have never been able to get the hardness where I want it. But in recent
months I've been increasing the calcium and therefore the hardness has
decreased. I've been concentrating more on calcium during those month than
the other. I add and tested for calcium and not hardness so I"m doing a
little backstepping now to get it all right.

I just read about the baking soda and may do that to get a jump back up.
Hopefully my calc levels will stay.

Just did some testing and got a problem. My water hardness has always
been on the low side of "normal" but not now.

pH is 8.4
Phosphates aren't registering
Calcium is at least 440
Ammonia, Nitrite and Natrate are perfect
I don't have a magnesium test kit but I add magnesium a couple of times a
week before calcium

The problem: my hardness is at 6 KH. I can't seem to increase that
number. My animals seem fine at night but who knows.

What can I add to directly pinpoint water hardness?

Thanks,
Bryan
