I replaced airstones with two koralia 3 circulation pumps. Will this give the fish air? Also, we have two cheap powerheads with filters. Can I take these out? Thanks
 
The way fish get oxygen is from the disturbance of the top of the water. If the top of the water is being disturbed then yes, o2 is getting in there (other components of air of course).

If the powerheads only use was to move the water around I'd say yes. (as long as your sump/filter wasnt relying on them.
 
Ok, great. Thanks so much jwddboy! Been wanting to get rid of these filters for a long time. thanks again!
 
yup, i agree with jwddboy. The fish should have plenty of air, and you can remove the other powerheads.
 
No, if there's air-water surface area, the water is being oxygenated. And the fish get oxygen from thier gills pulling o2 out of the water.

Thats exactly what he just said. It is proven that the more disturbance in the surface the more oxygenation occurs. The reason being is when the water is disturbed it allows for more surface area thus allowing more oxygenation.

On another note: How do you like your new koralia? I just received a Nano Koralia for my 10 gallon reef and I LOVE it so far. My other powerhead was a jet while this one disperses the flow and doesn't disturb the sand bed like the other one did.
 
Always drink your water from the most turbulent part of the creek.

If the water is not moving only the top layer will get Oxygenated. That top layer must get moved lower so the fish can utilize it and less oxygenated water gets a chance to come to the top.

If you have dead spots in your tank, that water may not be as good to drink as the fast churning top.

Well no, what exactly he said was that the fish get thier o2 from the disturbance... wich would mean that people running canisters on FW planted tanks with a surface smooth as glass should have dead fish... but it don't work like that.
 
Which they do get the air from the disturbance. How do you think there is air in water run through a canister? Disturbance. Is simple science. The more surface area the more contact to exchange air. Same thing with plants. The bigger the leave the more photosynthesis can occur which in turn allows growth.
