Adding 100% oxygen to tank?

i think in your situation heats going to be more of an issue then the gas exchange. i wouldnt put an air stone at all.

Also, air stones cause salt creep to become a major problem.

Reading this thread, did I come off harsh somewhere? If so, my apologies. Not intended.

No Pasfur you did not come off harsh. I misread your post and replied a little too quick. I went ahead and put an airstone in my sump with my pump. The water is churning quite nicely. Too bad there is no way (that I know of ) to measure the oxygen content of the water.
Maybe a little off subject but I am an avid fly fisherman. The best fisheries are those of tail waters.( below a damn). The water is highly oxygenated and the fish in these waters are bigger and stronger than any other type of fishery. IMO this is a direct result of the oxygen in the water, which in turn creates a great food source.
I am just trying to have the healthiest tank possible and looking at any options. Bruce

I'm admittedly a total newb... But looking at this from a different point of view. I would imagine the oxygen would gather beneath the top/cover and become fairly dangerous as pure oxygen is very flammable. Nobody mentioned this but I though it worth mentioning as I'm sure your goal is not to start your house on fire or worse yourself.

Adding O2 is overkill and the surface agitation is all you'll ever need. Anything that adds bubbles to the water that break on the surface will splash salt everywhere and cause you more problems in maintenance.

There are test kits that can tell you how much disolved oxygen you have in your water too.

If you have a sump than the water cascading down to the sump will oxygenate the water just fine. Adding an airstone will increase this, but is unneccassary, and will cause salt-creep, as others have mentioned. There is also a gas exchange at the water's surface, which is increased with agitation. I have my return pump outlets right at the water's surface to disrupt the surface. Partly for oxygenation, but more to keep the water moving and keep the buildup of that film of DOCs on the surface from forming.
