I bought a cheap acrylic bowfront tank kit with an intake whisper filter. does it have to produce bubbies?????

the instructions say to fill the tank to the colored rim, but when its that full, the ';waterfall'; from the filter doesn't produce any bubbles in the tank. My questions is, can the filter produce enough oxygen for the fish to survive?I bought a cheap acrylic bowfront tank kit with an intake whisper filter. does it have to produce bubbies?????
Love to know where that came from!





The tank instructions are somewhat correct. Where the colored rim is on the tank should be around 1/2 - 3/4 inches from the filter. The filter should POUR water into your tank. Dissolved oxygen which your fish use to breath, As long as your filter is pouring or RIPPLING across the surface, bubbles are not really a by product of this action. As long as you can see movement from the filter, it is fine as far as Dissolved Oxygen into the tank for your fish. No problem.





EDIT:





Dissolved oxygen can only enter water by movement of water against air. i.e. filters, powerheads, waterfalls, fountains waves etc. Bubbles rising thru the water has no contact with air. The few small pops at the surface of the water does nothing to add DO2 to the water. Bubble wands are for decoration only and are not needed in a tank. The oxygen is not absorbed by the water. It simply floats to the surface and that is it.I bought a cheap acrylic bowfront tank kit with an intake whisper filter. does it have to produce bubbies?????
The oxygen is located on the surface of the water. The larger the ';footprint'; of the tank, the more oxygen transfers. The filter isn't really to add oxygen to the tank. Bubbles don't actually add much oxygen either. When you think of it, the oxygen is encapsulated in the bubble...which rises to the surface and pops, expelling oxygen back into the air..laugh.


More effective is the water agitators, as they create rifts in the surface, thereby creating more per inch surface area.
Yes. There is a natural exchange of gasses from water to air and air to water. Also, the filter does not produce oxygen.
I always add bubbles for more oxygen, and my fish love it, they're never lethargic.
The instructions are correct... However you should know most of the oxygen in your tank does not come from the waterfall produced by your filter. If the water is circulating in tank that is enough to produce enough oxygen for your fish to survive.. Don't worry about it. However.. if you have a larger fish like a cichlid.. you might want to add a bubble maker.
