Species. Generally speaking, an oxygen level of
8.3 ppm (parts per million)
is sufficient for most freshwater tanks. This is because most fish species breathe through oxygen in water. However, some types of fish have evolved to survive in low-oxygen conditions.
Do fish need lots of oxygen?
To find out if airstones and added aeration are really necessary, let’s start with the basics.
Fish need oxygen to fuel their metabolic processes
, and like us, they will die if deprived of it for long.
How do I know if my fish tank has enough oxygen?
The most telling sign that your fish need more oxygen is
if you see them gasping at the surface
— they will also tend to hang out back by the filter output. This area of your tank tends to possess the highest oxygen concentration as it is near the most disturbed surface.
How much food should I feed my fish?
How Much Should I Feed My Fish? It’s always best to underfeed, especially in new aquariums, as uneaten food can cloud your water and cause dangerous rises in ammonia and nitrite levels. A general rule of thumb is to
feed only what your fish can consume in 2 to 3 minutes
.
How much is too much oxygen for fish?
Many people do not know that a fish tank needs to have a proper supply of oxygen. Since water is denser than air, there cannot be too much oxygen in the tank or the fish will suffocate and die. The proper amount of oxygen should be around
four to five parts per million
.
How much oxygen does a fish pond need?
Although it generally depends on the state and size of any individual pond, its best to have
at least 6mg per litre
of dissolved oxygen in any body of pond water. This ratio will keep pond oxygen levels well above the dangerously low ppm concentrations mentioned above.
How much oxygen do fish need per day?
The amount of dissolved oxygen needed varies from creature to creature. Bottom feeders, crabs, oysters and worms need minimal amounts of oxygen (1-6 mg/L), while shallow water fish need higher levels (
4-15 mg/L
)5. Microbes such as bacteria and fungi also require dissolved oxygen.
Do Small fish need oxygen?
Lack of oxygen will cause the fish to drown or suffocate to death
. Live aquatic plants can fix oxygen in the water, and also for most fish species plants provide them shelter and space for them to explore in the small confined area they live.
How long can fish go without oxygen?
Goldfish and their wild crucian carp relatives can survive for
five months
without breathing oxygen – and now we know how. The fish have evolved a set of enzymes that, when oxygen levels drop, ultimately helps convert carbohydrates into alcohol that can then be released through the gills.
How do you give fish more oxygen?
You can add oxygen to your tank by
slowly pouring water into it from some height above
. The water will pick up air en route as well as drive oxygen into the tank water. How much oxygen is added depends on how high above the tank you pour the water and how many times you repeat this procedure.
Are air bubbles good for fish tank?
An aquarium bubbler, also called an air stone,
adds beneficial bubbles to the aquarium’s water
. When these bubbles rise to the surface, they help the oxidation of water and improve the living conditions of fish, plants and other living creatures in the fish tank.
Why is there not enough oxygen in my fish tank?
Lack of water movement
also causes low oxygen levels because it is the movement of water that helps to aerate the water in the aquarium. If your aquarium has live plants then this could be a reason for the low oxygen levels in your aquarium.
How do I know if I’m feeding my fish enough?
Fish will eat as much as they need, so dispense the food in a few servings.
When they start spitting out the food, they’ve eaten enough
. If there is food remaining in the tank and floating to the bottom, you’re giving your fish too much feed.
How can I tell if I overfeeding my fish?
Whenever you see flake food resting on the bottom of the aquarium and no fish are eating it

Remove all rotting food and don’t feed your fish for a day or two
. Fish are fine with this and it will not harm them and it’s not cruel.
Can you measure oxygen in a fish tank?
The best way to test the amount of dissolved oxygen in your aquariums water is by
using a portable dissolved oxygen meter
. After calibrating this meter, you can then place a probe into the tank and read results on a digital display.
How long should you run an air pump in a fish tank?
How long should you run an air pump in a fish tank? First, do not run an air stone when you are adding CO2. Secondly, you can run the air pump 24/7 or you can put it on a timer and only let it run during either day or night time. I would suggest running it on a timer for
just as long as you are keeping your light on
.
Should I turn off the bubbles in my fish tank at night?
What is this? So,
if you have a really large fish tank and not too many inhabitants, sure, it is probably fine to turn the pump off at night
. However, if you have a lot of fish in a relatively small space, there might not be enough oxygen present to last the night, so in this case you should leave the air pump on.
Can you put too much oxygen in a pond?
More likely in a pond
you can waste oxygen by pumping too much in via an air pump
, oxygen is very important in a pond, particularly if it is heavily stocked for fish and in particular koi.
Can my pond have too much oxygen?
Too much oxygen could be harmful but you would really struggle to get that much into the water
. Supersaturation usually only happens with bore holes (under very high pressure) and you would see lots of little air bubbles forming on the liner and other surfaces (pump, plants, rocks etc.).
Do I need to oxygenate my pond?
Adding oxygen to a fishpond is very important to fish health
. This is particularly true in summer months and if the pond is heavily stocked. But even in ponds without fish an air pump will help keep the water fresh – particularly if a waterfall or fountain is not present or if your pond is deeper than 1.5m.

- Platies.
- Black Molly.
- Swordtail.
- Goldfish.
- Zebra Danio.
- Dwarf Otocinclus.

Can fish live without air pump?
Air pumps force oxygen into your tank by increasing surface agitation so your fish have lots of O2 to breathe in.
In many cases, your aquarium inhabitants don’t need the extra oxygen and live just fine without an air pump
.
