I'm still deciding on a CO2 method for myself. I have plenty of Excel left right now, but I'd rather not dose and have something automated.
I've seen these before in a LFS, and while they work, they're expensive. I know there are supposed to be versions of this from China that are half the price. Has anyone stumbled across these? How long would a block last in a 55-gallon tank?
The other question I had is how the pH controller feeds back to control the CO2. Based on what parts I've seen on a pressurized CO2 system, it would make sense that the controller is feeding back to the solenoid, but I've never seen a full setup hooked up. Can someone explain this to me?[/code]
