air pump failed help!
the air pump in my 10 gallon tank went out this morning. my question is; can i wait and get a new airpump in a couple of hours? there are no places open and i have to be at work in an hour. i can go on my lunch break and get a new one and replace it when i get off work.

its a 10 gallon, with an external power filter. i figure the power filter might give the tank minimal enough surface tension to keep the fish ok till i get home?? it has 6 harlequin rasboras and three habrosus cories. i know the cories ought to be ok, just worried about the harlequins.

Should be ok. :wink: You may wish to lower water level in tank to create more fall from water entering from filter. But probably isn.t necessary.

Air pumps aren't necessary. I use them because I like the look and my fish like to play in the bubbles. Your HOB will create enough surface agitation for sufficient oxygen.

Same here, never use them except for asthetics and certain specific needs like a blackout or really high temps. Don't need them at all. Any surface movement is enough to provide plenty of exygen for normally stocked tank like yours.

Coley and fish 4 all already said it. The bubbles from an air pump are for you, not your fish. The fish will get plenty of oxygen from the filter disturbing and moving the water around even if you never see a ripple on the surface. The water coming to the surface exposes that water to gas exchange at the surface. Unless the same water stays att the surface forever, the oxygenated water will move into the rest of the tank and the fish will have plenty of O2. I like the bubbles in my tanks and some of my fish like to play in the bubbles so about half my tanks have an air stone or other bubble sources.

I want to add that air pumps should be used at higher temps like 85*F when treating ich or other ailments. Water at higher temps hold less oxygen, but at normal (78*F) they aren't necessary.

Never mind, I see fish_4_all covered that. 8)

:wink: one of the benefits of running an airstone is.... In the event of a power failure the air stone will resume operation when power is restored. Some filters won,t without being primed. I have a battery operated air pump on my aquariums for just that reason. sometimes we are not at home when power is lost.the pumps I use will automatically come on if power is lost.Pretty cheap investment.
