And yer not, so I'll let THAT go. This time. :-)

Oh, goody. Another gadget.

No, a System 1. I have used the Magnum cartridge thataway, though.

Can't leave the System 1 on longer than four hours or it overheats. Would it
be better to use the Magnum, then?

I think I accidently did this. The Hot Magnum disturbs the water surface, so
I increased the CO2 to compensate. I was afraid of this, so I have been doing
it very gradually. Only this weekend did I finally reach a pH of 6.8. But if
I disturb the water surface, and then add more CO2, do I really have a net
gain of CO2? I mean, are the fish gasping because of too much CO2, or not
enough circulation, surface or otherwise?
