...if i wanted to add oxygen to an ebb and flow system i would...
1...add pebbles to the bottom of my table...it gives oxy bubbles a place to cling
2...put a 'tee' in line with my water pump, just above the water line, so that while my table fills water is splashing into the res...assuming you have a submersible pump...if you have an in-line pump, install a .75 grommet between the pump and the res so as the table fills oxy gets sucked into the line as well...

E&F by design allows maximum aeration of the roots and does not require an airstone BUT on the other hand the health of your reservoir will benefit from one. In other words airstones are a good thing always and to answer your other question airstones should be run 24/7 of course. GL

...did you know that air stones actually release oxygen from water?..if you take an o2 sample from water befor adding air stones then take a sample after you turn the air stones off, the ppm of o2 is lower...breaking surface tension with o2 causes an increase...
...and yes, dcyans, airstones on constantly create a healthy res environment but we must ask why...

Yeah, Man, for the health of the stuff in the nute soup. I never agitated until I used organic nutes, and found out it was recommended for the critters. I don't use those nutes anymore, but do use organic supplements, so I still aerate each res.
I don't know about changes in the O2 levels, but I do know that the air is mixed at the surface, and all an airstone does is roil the surface. So I just run a water pump in the res that moves the surface.

understanding that, is an airstone at the plant level ok? we have one at plant level and one in the res.

Ohhh, in the bed with the plants that fills up! I gotcha, but it's not necessary. What you want to do is have the airstone in the rez, and running 24/7. That will keep the soup oxygenated, and any critters living in it will be happy. When you flood the bed, it will be with well-oxygenated soup.
cool... thanks.. right now the airstone runs when the pump goes on. but it's a easy change to a 24 hr plug.
thanks
I don't know where you get you're info but oxygenating water in a closed reservoir
does not decrease or release O2 from the water. Dissolved oxygen via aeration is
an O2 enrichment and unless you already had artificially high O2 levels aeration is
going to raise PPM of O2. I've worked in both hydroponics and aquaponics for years
and have never seen an O2 test indicate what you're saying. Using air stones is a
must for effective maintenance of reservoir quality.
