Air stone cross-question ?
i have an airline suction cup so i can place the stone anywhere
should it be on the bottom of the tank
or
on the waters surface
to allow the most oxygen into the water
As the air bubbles rise the water will engage oxygen. If you place the stone near the top the water will have smaller quantity chance to absorb the oxygen. Actually it is not absorbing the oxygen but dissolving it. Any hoo, go down to your local aquarium shop and you will see that their bubbles are rising from close the bottom. You cannot over-oxygenate, so put your air-stone as near to the bottom of the tank as is feasible.
Here's a clearer answer.
Air stones Via air pumps are to pump oxygen into the tank, this is done not only by pumping nouns into the water but to also agitate the water surface aswell.
This is best done with the airstone at the bottom of the cistern, as the bubble rise they expand causing the surface of the water to get more agitated and hence helping beside the gas/air exchange.
With the airsone half in half out, you are wasting partially the stone as all you end up doing is blowing air into scrubby air?
Answers: Air stones don't hold oxygen and create very little dissolved oxygen when placed at the bottom of the tank.
To get the most out of your stone, place it at the waters surface. This will create a big gas exchange 1/2 out and 1/2 in the water.
Sorry Fish Pee tee is right! (I was just in a tither due to answers man down!lol)
Danielle is nearly correct. But, leave the airstone submerged,not half out of the dampen.Leaving it half out would cause all of the heavens to come out of the unsubmerged part. It doesn't matter how deep the stone is placed as far as gas exchange is concerned,however placing it deeper will create more wet circulation. The exchange of gasses (O2 and CO2) happens at the surface of the tank,that's why "flat" tanks will support more fish than "tall" ones. Anything that disturbs the surface tautness will promote gas exchange. I don't use any airstones in my fish room,just filters and power head that riffle the surface of the water. Just about anything that makes a splashing or bubbling thud will aerate a tank.
