Ok i just baught one for my fresh water stingray tank for more oxygen because i heard how good they work. But do they just move the water around or do they actually give out oxygen. Thanks for any infos

They create water movement...

If you direct them at the surface they will create "surface agitation" which encourages gaseous exchange at the surface (including water taking on oxygen)... and will also circulate oxygen rich water from the surface to lower regions of the tank...

We read a lot about the importance of "surface agitation"... but very rarely hear talk of the importance of circulating that oxygen rich water down into lower regions...

Proper circulation has many benefits...

No aeration, but great gentle current & movement
