How To Quickly Increase Oxygen In The Tank? I highly recommend you to check this battery-operated air pump (available on Amazon) that can be super handy at times of emergency situations like power cut-off. And if that is not possible, at least have a battery-powered air pump to use in case of power outages. Have inverter systems that enable you to run electrical appliances in your home. So better be safe than sorry and take adequate precautions. No fish were harmed 🙂īut what I’m trying to say is that as soon as you see your fish gasping for air, consider it an alarming signal.Ĭaution! On average, in an ‘oxygen depleted tank,’ the aquarium fish don’t tend to survive more than a day. Don’t worry in all the cases, we were active enough to make the air pump run again or find some alternate oxygenation source in the tank. I have seen our fish gasping for air, and in many cases, the culprit was that our air pump stopped working.

When there is a lot of fish in the tank, higher will be dissolved oxygen usage from the tank water.Īs the water is limited, the oxygen dissolution in the tank water is limited a time comes when the fish starts to feel a lack of adequate oxygen. To give you a better analogy, it is similar to when we go to a big hall jammed with many people. If you have very few fish in the tank and many plants, your fish can survive in normal conditions without any filter or air pump.īut the problem starts when there are lots of fish in the tank.

So why then do we need to worry about fish in the aquariums? Well, the water in natural conditions is, in most cases, moving water and has enough surface area.Īs long as the fish can utilize the dissolved oxygen from the water adequately, they can easily survive!īut in our aquariums, the water remains ‘still’ when there is no air pump, no filter, and no air stones/bubblers. Do they need oxygen support, like an air pump or filter? Nope! In natural conditions, they just live in rivers, ponds, or streams and rely completely on nature. Just think about the life of fish in nature. In most cases, fish can survive such lengths. So you don’t need to worry if it’s only a matter of a few hours, like 4-6 hours. However, we never had any issues with fish dying because of a lack of oxygen! And sometimes it would even last for about 6 hours. Here where we stay, we sometimes had to face about 4-5 hours of power-cut. If you live in a power outage-prone area, it is important to take precautions.īut honestly, here’s what we have experienced in our case.

Providing oxygenation sources won’t harm any fish unless the water current becomes too much for them.
