Are you that attached to a metal container with compressed air? It doesn’t match your hair and makes your feet look big you know…
Is this a joke? people who take their oxygen tanks with them usually need them to breathe! some may be hypochondriacs, but generally it’s a life or death situation.
I think there isn’t enough oxygen in the tank cuz I read that’s what happens if the fish are always near the surface of the water.
Is there any way I can do it w/o changing the filter or tank?
Just get a bubble stone or bubble curtain for your local petstore. Unless you have a HUGE tank (30+gal) then you should look into aerator systems. But if you can I’d try the bubble stone, it’s less expensive.

"Sharon and Steve need to design a data chart in order to record the measurements they made during an experiment. They had a tank of oxygen gas in which they increased the pressure from .5 to 2.5 atmospheres of pressure in increments of .25 atmospheres. They were to record the temperature every .25 atmospheres in degrees Celsius. They added a column so that they could later convert the temperature to degrees Kelvin."
I got as far as making the column for the increased pressure, but I don’t really understand how to find this data solely from the paragraph in the quotes. Any help is appreciated, as i’m totally stumped.
Sorry, i’ll make it a bit clearer.
I’m supposed to make a data table showing how many degrees in celsius and kelvin each .25 atmospheres of pressure in an oxygen tank become.
The thing is that I don’t really understand how to find it out.
So, you need the ideal gas law:
PV = nRT
You are recording P vs T. R is a constant but it’s unclear how you are achieving changes in pressure – you must either reduce the volume or add more oxygen (or both).
Anyway, let’s simplify and assume (for argument purposes) that both V and n are held constant.
The relationship between P and T (with everything else held constant) is usually expressed as
P(1)/T(1) = P(2)/T(2)
(Of course, T must be in degrees K for this relationship to be exact.)
Now, when you plot the P vs T curve, you can tell whether the equation, above, is followed or whether yo need to account for increase number of moles (to increase pressure) or to decrease the volume (again, to increase pressure)
Good luck
1. Find oxygen tank (There is always at least one in the chapter)
2. Make to the Elevator while holding
(DO NOT DROP THE TANK IN THE ELEVATOR, THERE’S A WEIRD GLITCH/ IF YOU DROP IT NEAR SOMEBODY IN THE ELEVATOR THEY FALL THROUGH THE ELEVATOR AND DIE !!!
3. Put down oxygen tank in front of generator with the “Y” button.
4. Shoot the tank.
Done 
Btw don’t get Boomer bile on you, it’s bad stuff.

I’ve got a small unfiltered tank, would plants provide enough oxygen for a small number of fry in there or would plants make it worse by using up the oxygen at night?
Plants only produce oxygen when there is light for photosynthesis. When you turn out the lights, the plants will start USING oxygen, which is an easy way to suffocate all the fish in an unfiltered tank. Even an air stone would help. Really, the only way to even consider keeping fry (other than Anabatoids that can breath air) in an unfiltered tank is if you do daily water changes and have some sort of surface agitation to oxygenate the water.
I got tired of buying the 1.4oz tanks that Bernzomatic sells for their torch’s, so I got a 20oz oxygen tank to save money. What I’m wondering though is just how much more dangerous it is to use a larger sized tank in the same hand torch. (it’s a $50 oxygen/MAPP welding/brazing torch)
As long as you regulate properly there is no difference in the size of oxygen tank you use
We shot a portable oxygen tank with a .306 & that blew up! Cops came saying they got a call about people lighting off dynamite and that the boom broke a neighbors window.

Assume for example a starting fire in a bed or a carpet.
Sure, I can imagine a number of scenarios where this could happen.
But they are all very contrived.
O2 is not combustible.
So lets say that there is a propane torch flame burning in the middle of a concrete room. And I rupture an oxygen tank near by.
I believe what would most likely happen is that the rupture would blow out the flame. It is also possible that the flame would just increase in temperature and brightness (and perhaps size).
replace the O2 tank with a propane tank, rupture that and kabloowie!
The O2 concentration affects the speed of combustion. Some things will burn under high O2 and not at normal 21%. In fact there is a test, the OI test (oxygen index) which measures the oxygen concentration necessary to support the burning of a material (a plastic or fabric for example). Anyway something which might burn "normally" at 21% O2 might burn very vigorously under 100% O2 and cause a explosion.
Probably need something with a lot of surface area (fabric?) and a lot of it.
