Can't figure out which lines connect to which. I presume the bubble counter should connect to the CO2? And then the other "Filter" thing (as described in instructions) should connect to the pump drawing water from the sump. Then the floppy long tube goes back into the sump with water charged with calc. Is this right?
If so, the attachment to the pump needs an adaptor before I can attach it to the hosing for the pump.
It's more complicated than I thought ..
