How can I stop my under gravel filter to make bubbles at the top of my tank?

Question

3 days ago I bought a 2 gallon aquaruim kit with an undergravel filter for my Betta (yes, NOW I know they are not the best, but I didn't know that when I bought it and don't have the money to upgrade right now) but there are many bubbles coming from the filter and they stay on the top and don't brake! there just a small "calm" space for the betta to go out and breath air... how can I make the bubbles stop? :(

Answer 1

It may be that the air pump you have is too large for the size of the tank (if the overall flow is excessive), or if the bubbles just don't pop right away, this may be caused by the type of water conditioner you use, or by too much organic wastes in the tank.

If the problem is too large of a pump, you should be able to get plastic valves that allow you to control the flow rate (http://www.thatpetplace.com/pet/group/10420/product.web ) at any pet store with the airpumps, tubing, and related supplies.

Answer 2

Regulate the pump, Betta don't need that much air, by the way they produce bubble when ready to mate.

Answer 3

you actually want the bubbles to aireate the water. if you really dont want aireated water. take it out and at the bottom of the tunnel thingy there should be a little stone type thing, called air stones. you just remove that!
