old set up on my tank 4 XL sponge filter 2 bubble disk and 3 2" stones all ripping the water at full force never had one fish die...
over aeration cause pH to raise??

I pulled some books off the shelf. The only thing I discovered is there is lots I don't know about water.
A bubbler will not add a reasonable O2 to the water, but rather just cause surface agitation, which causes gas exchange at the surface. If higher O2 levels were to cause higher pH and hardness, then w/d filters would not be suitable for low pH low hardness tanks. In order to really cause a change, if it is actually possible, you would have to be injecting pure O2 into your tank, with no surface agitation, and have either an O2 reactor, or a great diffusion method to cause extremely elevated levels of O2.
I am agitating my tank with 2 xp3 and a xp4 with the outputs above the water surface so that the jet of water skims across the surface. This causes a lot of surface turbulence for about half of the tank (71" x 34" x 31"h). I also have 4 large sponge filters (hydrosponge 4) with 2 MJ1200 ph. I have not noticed any ill effects and my rays seem to be healthier.

Ewurm says air stones/bubblers DO add o2 to the water...I was always under the impression that you posted, and wurm provided a link with a ton of info stating the opposition...Seems like even the facts are disputable in this hobby....

the only problem is in a tank with high co2 such as a planted tank and even then it is not massive .in a normal tank with no co2 injection you can not over aerate, as the water can only hold so much oxygen.
IMO...i put just as much aireation in the tank to produce water movement from bottom to top. i never put as much as creating fine bubbles to get caught in the gills....and plus it makes the water look dirty.
