Oxygen injection

  • We are currently upgrading MFK. thanks! -neo
I thought I had read something that explained why it was a bad idea, but it was for air, not pure oxygen. too many microbubbles actually attach to the gills preventing water from reaching them.
not quite the same thing you're talking about. I posted before verifying.:duh:
I have read that humans will actually get oxygen poisoning, but that's under greater pressure that forces it into the bloodstream.
 
I've used hydrogen peroxide oxygenators like these in the past: http://www.aquariumoxygenator.com/

I used them quite a bit in the late '80s / early '90s....and they're awesome, especially if you DIY the Hydrogen Peroxide mix.

Imagine a source of oxygen for your tanks that's not dependent on electricity and is totally silent.

They work like a charm.

Here's a DIY version: http://www.coloradoaquarium.org/pics/oxy.html

I'm with the Old Dog, I've never heard of this, either!

Oxygen can be harmful to humans in concentrations greater than 60% for sustained periods under normal ambient pressures, it's called oxygen toxicity and causes the release of free radicals. Your reference to greater pressures just speeds up the process that's why people under going hyperbaric oxygen treatment have to take what is called a oxygen break and breath 21% oxygen through a non-rebreathing mask for 10 minutes after 45 minutes of therapy while still in the chamber other wise the will start to ceasures. In infants oxygen toxicity causes things like retinopathy of prematurity which is a condition where the retina actually becomes detached causing blindness. I haven't got a clue as to the effects on fish though, will be interested to see what develops.
 
I don't want to discourage you because I have no idea how an oxygen enriched environment will affect fish but after going back and reading more of the post most of the things mentioned so far aren't really accurate and sometimes oxygen could even be considered the snake oil of our time. Oxygen used to fill your welding tanks is not the same as medical grade either. FDA monitors medical grade oxygen pretty tightly because it is considered a medication, prescribed by a doctor and is sterile, where your welding oxygen can be full of impurities.
 
I have done a fair amount of research on this.

1. Fish farms inject pure O2 because their stocking densities are insane and no amount of airation could keep up.

2. Injecting pure O2 would be a waste on any aquarium.

3. I plan on injecting normal air into my CO2 reactor with the CO2. The normal outside air will get completely dissolved in the reactor. This should be able to achieve 100% O2 saturation for the temp our tanks are at. Warm water actually wont hold much O2 to begin with.

I buy my welding oxygen at aaba medical supply.
