Richard Posted September 14, 2003 Report Share Posted September 14, 2003 Just wondering...with the water pumps... they have a tube that extends outside the tank to get air and create bubbles.... if i do not use this tube... and there are no bubbles...but the water still moves.... does it mean there is less oxygen created???

Matthew Posted September 14, 2003 Report Share Posted September 14, 2003 from what I understand some people will argue that the bubbles do nothing, and that it is the water turbulence at the surface that encourages the absorption of o2 into the water. I think that bubbles aren't necessary, but watch your fish, if they are gasping or acting strangely then maybe that would be beneficial.

Caryl Posted September 15, 2003 Report Share Posted September 15, 2003 That was my understanding too. Quote Link to comment Share on other sites More sharing options...
