i run a wet dry and supposedly that should be a great way to aireate the water. is it? i have a sick ray and i finally turned on a bubble strip and 2 powerheads with airlines. he's a tad more active. how much aireation is needed? can too much be bad? i have a 100 gal, with 2 good size retics (9" and 7 1/2") yepezi 4". 18 " longnose, 15" lima.
 
Do u know what is wrong with ur ray?

Yeah I use a wet dry and it is good at aerating. Lots of circulation and my water level changes (pulsates?) for good 02 exchange.

I got air stones too but i hear they are not good for oxygenating.

If ur really worried, buy some oxygen tablets from ur lfs, they're cheap.

Dont know how much is needed but if there are tiny bubbles all thriugh your water, that is too much!
 
You can actually super-saturate a tank wtih air. It is highly temp dependent, and I haven't seen it too often in smaller tanks. Usually it happens if a pipe cracks and starts forcing air into the water or you end up pushing it in some other way.

There are DO (disolved oxygen) testing methods out there using various tools and probes. Most likely, it's not a problem.

It sounds like you have good circulation in the tank. A quick way to tell if the DO is low is by watching the amount of gill activity you see in the fish.
 
Jst make sure you have a PH or some other piece of equpment breaking the surface of the water. More surface area in contact with the air will make for more O2 exchange

Just think about still water compared a nice rippling current at the surface.

Top water current(rivers)=high levels of O2

Still water(swamp)=low levels of O2
