Hybrid venturi/vortex aeration system for RDWC

[Northern_Loki]

Cool beans. I like venturi injection concept, in part, for the benefits you’ve noted.

Here is an attempt at using venturi injection along with a needlewheel pump.

Airpumpless Sluckets

Here is an experimental set-up utilizing “slucket buckets” in a, more or less, DIY configuration. [image] Slucket buckets have sloped bottoms along with a bottom port allowing for improved drainage over conventional RDWC type set-ups. Water is injected from the bottom ports on each of the growth modules while water is removed from the bottom port at the reservoir. Return from each of the growth modules is via a 3 inch diameter pipe. Several valves comprise the pump manifold allowing the dir…

Data collected in some trials has shown relatively fast DO saturation (and possibly) exceeding 100% DO for the temperature / atmospheric pressure.

How about starting a thread on your work / discoveries?
