Air Tubing:
This simple component while not necessary for an algae reactor to run is really crucial in my mind. Aerating algae both agitates it so it gets uniform light exposure as well as introduces more CO2 to the mix. This air hose we picked up from a local aquarium supply store for 2.00USD and is far more than we need for this project (so we have more for future projects). It’s worth noting that this hose doesn’t react well to long term direct sunlight exposure, a simple UV resistant clear coat though makes it last much longer.

The Hose Fittings:
We found these barbed hose fittings at our local home improvement center. I really have fallen in love with these little guys. They provide a simple connection that is secure yet removable. This makes it easy to vacuumed fill the tubes from the bottom with a siphon hose. Use a plastic zip tie to secure the hose to the barbed end for long term unattended use just in case.

Plastic Dip:
This stuff was one of the major advancements for my reactors. The tubes are dipped into this stuff and allowed time to totally cure. This provides us with 2 great features; it’s totally waterproof and has tremendous shock dampening ability. So the weather and wind and even hail can blast your array and you can rest assured its safe.
