ditto on what Marc said, plus if you dont test for it DONT ADD IT.

but now I have a
Calcium Reactor and it does it around the clock.

humm kewl forgot you had one of them, hows it working, ive been using one
for what seems like forever. if i recall right you got one with your big
tank??? did you get it dialed in good ??? i thought i recall you saying that
it wasnt correct, or something???

No other supplements are dosed in my tanks.
I do kalk also thru a kalk reactor cause im lazy and i dont like the low
tank ph.
