That thing is way overpriced. The whole thing sits on a very simple method of splitting the water to oxygen and hydrogen.

In big system I’d be worried about the hydrogen gas...


I was looking around and saw 2 more very interesting thing.

First one called Carmin. I don’t really get how it works but absolutely looks awesome in action.


And here is the other technic that easily can create nano bubbles.



Let me know what do you think, I’m total new but these methods look more efficient than air stones.

I am a sucker for increasing oxygen in my rez, but it seems we don't 'need' to go to such extremes

Simple DIY flooming will provide all a small growers rez needs.

Lots of ideas on YT

I have my flooming pump on a deep cycle timer 2-3 minutes on and 20-30 minutes off is working just fine. Longer times can cause the pump to heat up and therefor the nutes

Flooming works just as well.
A simple pump on the bottom of your reservoir, with the exit pointing towards the surface of water.

Maximum DO-levels are reached so easily.
The only problems can occur when the root-mass becomes so thick that the water inside the root-mass does not move anymore.
So just water without any oxygen at all.

I don't know if I believe flooming the res alone is enough for 8 buckets man...
But if it is, this will only be extra movement. I'm just a fan of the waterfall method rather than a full circle of PVC to move around. I'd rather bring the water back in to each bucket from a line.

In commercial greenhouses that use waterbased systems they grow all kinds of plants and crops.
Herbs, lettuce, vegetables like leeks and chicory, flowers like chrysanthemum, a wide variety.
A lot of them use a system where the plants are in a large basin, on styrofoam with some air underneath.
The water stands still for most of the time.
The only thing they do is put on a pump for 5 minutes per hour, so it makes the water circulate.
That is all they do to get DO in the water.

a long time ago I wondered whether putting the input to each RDWC bucket up high thus creating a waterfall into each bucket. It takes jut a few elbows and some extra tubing to experiment. It might require a larger pump

I got rid of them by running a 1600 GPH pump from a res to 8 5 gal sites using a manifold and lines to water fall into each bucket from a 90 coming out the side wall through a grommet pointing downwards. 2" pipe and uniseals are at the very lowest point on the sides of my buckets kinda like an undercurrent system but my return is gravity fed and the fast flow of water, waterfalls, flooming in the res, and of course a chiller, I've accomplished a quiet RDWC that uses NO AIR PUMPS OR AIR STONES, with more than enough dissolved oxygen and I couldn't be happier.

As far as the totes on top shelf, they're now aerated by a venturi style fertilizer injector with an airhose just connected to where fertilizer is usually drawn from, to outside the tote for air suction, with 1/2" in/outlets connected to a pump on its side moving everything through it .

The mini RDWC system has also since been upgraded to 2Gal buckets with uniseals and 1-1/2" pipe gravity return lines for the same thing as my main. Only difference is an INLINE pump to supply the manifold so my water isn't heated as there's no chiller on this smaller 13-15gal of water system. It's Killing it without the help of air stones/pumps as well.

I'm so relieved to get rid of the nuisance and sound of loud air pumps.

waterfalls in an RDWC is what allowed me to get rid of airpumps/stones
