Micro Bubbling

[Cruz_Arias]

What you say has nothing to do with the actual scientific reason and evidence of why nanobubbles have a negative charge (which has to do with the crowding of different ions ions at the tiny curved surface and the fact that hydroxide ions are slightly more prevalent there than H+ ions).).

Being that OH- is more prevalent, that would create a more negative net charge locally.

In your tank or ours, Randy?

The devices you use.

Sorry, where did it say bacteria have a net positive charge? It doesn't.

Ahh ok... yeah, we see lots of observed benefits. But once again anecdotal but, we can grow some crazy sps though. So whatever we're doing, we wanted to share.

It says it depends on the membrane phenotype... and using dielectrophoresis to separate good bacteria from bad, the bacteria being acted upon need a net charge to be affected, either positive or negative.

That's certainly a reasonable claim. :)

Yes, but you separate them based on charge to mass ratio (or some function of mass and volume that imapcts their diffusion with a given charge in a given field), sort of like in mass spectroscopy, and it still works even if they are all negative. :)

DEP is similar to electroplating... utilizing cathodes and anodes...

Positively charged particulates or bacterial organisms travel towards the anodes and the negatively charged particulates or organisms travel towards the cathode...

Pretty interesting stuff that also goes beyond me... lol

I'll send you a video (HD) of the extremely small bubble mist we generate.

It's a lot finer than microbubbles, Randy... that's for darned sure!

Its an enthusiastic thing. Id try it it cant hurt. So just put an airstone in the intake of a pump?

But why doesn't a skimmer perform the same way?

If creating a charge is desireable, is it beneficial to disconnect a grounding probe?

 

[Cruz_Arias]

We place the wooden air stone in the weir before the return pump chamber.
This is a controlled method... and you'd need an air line valve to control the air volume going to the diffuser.

A skimmer works similarly, but the addition of the bubble traps have isolated any benefit from micro bubbling that we have seen prior to bubble blocking.

Also, most do not run a fresh air line to their skimmer air intake and suck up a lot of metabolic waste gasses that degas in the overflow return chamber in the sump area (typically this area under the stand has poor ventilation and poor air quality)

Thought I’d bring this post back to the surface.
Contrary to old reefing methods where we avoided bubbles as they were said to be trapped in the fish gills or killing corals .

has there been any further testing ?

I certainly heard if a number of folks that use bubbling, but I do not recall seeing any actual quantified testing recently.
