"Yes all airlift style pumps including geyser style must have their water intake submerged to some extent. Attached is a chart for the Kondo geyser pump showing submergence ratio and efficiency. They show a ratio of up to 1/10 for the geyser ejection…"
"Fredrick check your facts on the pumps. The air lift style must have its lower end below the water surface the same distance as the outlet is above the surface, not twice as much.
The geyser style pumps do not need this submergence at all."
"A wind powered air compressor can definitely be built and used to pressurize an air tank. The compressed air is stored the same way as electricity in a battery. From an energy conservation standpoint, this would be best because converting…"
"My wife and I are what most people call hard core preppers. We have been doing conventional gardening for a few years now and really want to transition to aquaponics. We are really concerned about sustainability so we need to know what kinds of…"
"I watched a few videos with Glenn in them showing his work. His pumps are definitely geyser pumps and they work great. did actually mean the fill/drain cycle btw. Anyway, I see now that trying to match up the geyser pump slug to a fill/drain cycle…"
"Thanks for sharing your research. I am a wannabe aquapon. I have done rudimentary research on the geyser pumps and believe it to be the most efficient way because you aereate your water the same time as pumping it in slugs. Since pumping water in…"
