Airpumpless Sluckets

I’ve been on pause for the DO experiments. I’ve cross posted some DO readings that I took last year into Slain’s thread, here:

Hybrid venturi/vortex aeration system for RDWC

For reference, here are a couple of plots from some tests I did last year on DO (no plants) under different operating conditions: [image] [image] For these, there were four modes of operation: pump speed set to low with the venturi off. pump speed set to high with the venturi off. pump speed set to high with the venturi injecting air. pump speed set to low with the venturi injecting air. The initial “high” DO is from the municipal source supply, which, as can be seen, eventually out-gases.…

Still “in-progress” otherwise, FWIW.
