Yet another bubbler question

[fish_freak]

I took the bubblers out of my tanks long ago cause I dont care for the nose or the look and once I found out they didnt do much i figured it was pointless. Well I bought a Jag and I have read they like highly oxginated water as they are from rivers mainly in there natrual habitat. Any way I was wondering if any one knows if there is acctualy any studies out there that can show oxygen concentration with and without a bubbler. I have heard all the opinions on this matter and now Im just kind of looking for some facts. Now on my 90 gal is 2 AC 500's (110) and a magnum 350 canister makeing surface agitation so Im thinking Im fine on oxygen sat. but just curious.

Im not sure if there is an easy way to test for disolved O2, but adding an airstone will definatly help increase it. I highly doubt it is needed. If you get a better stone than the cheap 25 cent ones it will put out smaller bubbles, and thus increase the ammount of surface agitation.

I have a Red Sea Deluxe Fresh Lab test kit and it has a liquid test for O2. Its increments are ppm, and it includes a table of maximum saturation of oxygen in water of various temp's and salinities. The test is a little hard to do, though, because every time you open the test tube to add drops, you introduce oxygen. And when you stir it, you add more oxygen.

If you're really interested, you can also buy an electronic oxygen probe, but it runs in the $250 range! It's what we use at work and is great because you just swirl it in the tank and it comes back with a reading, either in ppm or % saturation as well as some other units.
