Is there too much aeration in my tank?

Hi. I have an 11 gallon tank with two goldfish. I have an air pump that says it is suitable for tanks up to 39 gallons. I have it connected to a 10 inch air stone to create a wall of bubbles at the back of my tank, as well as an internal filter. There is no problem with the amount of turbulence in the water, my fish have no problem swimming around and enjoy swimming in the bubbles and at the filter where the water is blown out.

I was just wondering though if there could be too much aeration in my water? I have read online about the gas disease that fish can get and it has me worried. When the air pump is on (I turn it off at night but keep the filter on) there are a few tiny bubbles floating around in the water. Is this a dangerous level of aeration? Should I get a smaller air stone?

Thank you .

 

Welcome to Fishlore. What kind are your Goldies? How old are they? How long have you had them? What kind of filtration you have? I hate to tell you, but 10 g is not suitable for any goldfish. Fancies some require 20 gallon for the first one, and10g got each additional ones. Koys should be in the pond.

 

Tank size depends on the type of gold fish you have, so check the size they will grow to. Certainly Kois would be too large for an aquarium. Some fish have an inbuilt system which allows them to grow only to the size which is suitable for the area of water, so in a 10 gallon you'd probably be ok if they are not really big ones.
As for air bubbles, they do help to oxygenate the water, which is obviously beneficial for the fish.

Actually from what I have read, this is not true. Fish still naturally try to grow to their normal size. In smaller tanks they have stunted growth which affects their internal organs and stress levels. I'm no expert on goldfish, but I know that there is not a goldfish in the world that would be healthy in a 10 gallon, let alone 2 of them.

To the OP, welcome to fishlore. As for the aeration, I don't think you have too much aeration it helps for gas exchange. But I would seriously look at rehoming your fish and getting something more suited for your smaller tank. In time those goldfish will suffer immensely, even if they are very small right now. Please read up on some info for goldfish and you will find they need much larger homes. Try googling "goldfish care" or something like that, and you will find a wealth of info. You can also google "10 gallon aquarium stocking" to get some ideas of things that would be better in your smaller tank.

 

Welcome to fishlore!
I agree with Jomolager and Dolfan, goldfish get too big for a 10g.
Your airation is fine.
