The CO2 System

I wasn't going to use CO2 on this tank, but I just love ADA's glass work and wanted to use their beetle counter and pollen glass. This CO2 system is relatively cheap and comes with a disposal CO2 canister, stand and regulator.

This is ADA's Beetle Counter. To be honest, this bubble counter is overkill and a bit big for my small tank. But I figured that I could re-use it when I upgrade to a large tank. Besides, this CO2 bubble counter is a work of art. The CO2 bubble rises in a spiral instead of straight up. What's the benefit over a standard bubble counter? None! It's just nice to look at.

I couldn't resist this all-glass check valve for the CO2 system. Beautiful to look at and almost 100% reliable unlike other cheap plastic check valves. The little, red glass ball is the valve and seals completely if there is any back-siphoning.

ADA Pollen Glass Mini. It contains a diffusion plate to aid absorption of the CO2 into the water column.

I plan to shut-off the CO2 at night so I bought the solenoid.

And I bought a cheap timer for the solenoid.
