oxygen rich

[Scatocephalus]

I remember reading an article years and years ago about a guy, in Texas I think it was, that kept his oscars in essentially a hyperbaric chamber. They supposedly grew to almost 24".

There is a theory that the reason animals grew so large in prehistoric times is due to an oxygen rich atmosphere. The atmosphere changed when a giant meteor hit the earth.

For what it's worth...

yes agreed. and after each ice age the o2 rise untill they say it reached too high and the atmosphere became so enriched with o2 that lightning striking the ground would cause massive explotions. i think out current o2 concentration is only ~20% where in those times it was almost 80%... i belive it,

Many years back they would put athleats in pure o2 chanbers when the hot realy hurt and they healed up 5 times faster. with fish i think that if you went too high they would pass out and drown(sounds dumb i know). i probly wouldnt pump o2 through the water but like Scatocephalus said put it in a hyperbaric chamber so you dont rish blowing up your house when lighting the stove...

woulnt the pressure of the o2 in the tank make the o2 tank thing run out way to quicly making it needed to be replaced every 3-4 hours after constant injection? just a thought.

It seems logical that when plants "breath" more CO2 they grow faster so that means when fish breath more oxygen they should grow faster. But thats not the way those processes work.

Plants do not actually use CO2 the same way that O2 is used in animals. CO2 is consumed and processed into sugars which are stored in the plant, so mass is accumulated. Here's a great animation of exactly what goes on during photosynthesis.

O2 is used in the breaking down of those sugars and actually exits the body with a carbon atom (CO2) so mass is reduced.

Plus, oxygen tanks are way more dangerous than CO2 tanks. They are at much much higher pressures (knock a nozzle off of an O2 cylinder and it will go through pretty much any solid object in its path). Also, as someone mentioned earlier, an O2 leak can be just as deadly as a gas leak.

There was a product in the late '80's / early '90's that was essentially a hydrogen peroxide reactor for fish tanks...that produced oxygen in the tank.

It was (as I remember) a green plastic rectangle that sat in the tank. You filled it with hydrogen peroxide and added a pellet to produce O2.

The thing worked well...almost too well. I did an experiment with a male convict in a 20G and added double (triple?) the number of reactor pellets...The convict developed bubbles in his fins that went away only after removing the reactor.

I don't think they sell these things anymore but they proved awesome when I had power outages (and not enough battery-operated pumps).

I remember those. They were marketed as a tank cleaning tool. The high oxygen levels would help to oxidize waste thereby making it unneccessary to clean the tank or at least go much longer between cleanings. At least that was their claim.

lack of oxygen is one of the reasons "they" think payara never reach there full length in home aquaria. they come from white water areas that are very high in oxygen. This could probably also be said for S. rhombeus too. I think that there are some people that are now trying to recreate this in aquariums.

Interesting...

When I say to put an air stone in the tank many scoff and say it won't raise the oxygen level...so what make everyone think that using straight O2 will be any different? Without doing so in a pressurized chamber.

O2 & CO2 injection are both difficult to accomplish and and are best done...

A.) in a pressurized chamber (your livingroom may get mistaken for Micheal J.'s)

B.) With a plate over atleast 80% of the suface area of the tank to temporarily seal the surface and hold the gas in contact with it longer.

With proper safety precautions I say do it...

MMmmm MONSTER GUPPIES... Their not feeders any longer...

Couldnt you just inject it using a diffuser like when injecting Co2?

ill just stick with the 3 air stones in my tank and use the money ill save from not buying oxygen to buy more fish
