Airstone Better Than Filter Produced Bubbles

[restricted_alchemy]

Both my tanks have filters with venturi values to introduce air in the form of lots of bubbles into the outward flow of water.

Is this good enough that I do not require an airstone? The fish don't seem deprived of oxygen at all so perhaps that answers the question?

prescisely

if it aint broke don't fix it!

what symptons indicate that your fish arent getting enough oxygen?

Gasping near the surface, red gills ( although that can be an infection too), heavy breathing, panting gills. Just like me when I've ran for a bus. Although I don't have gills.

Having powerheads and filter outlets that disturb the surface is far better than almost any air pump can offer in terms of aeration.

The bubbles from an air pump are not in the water column long enough to allow a meaningful amount of air to dissolve into the water. The bubbles will cause some surface agitation, but not as much as well placed pumps and filter outlets.

i have ex700 external filter and a aquaflow 1 internal filter running my 4ft tank. The water is pretty clear from the front but down the side its murky. Its been like this since i set it up 4 months ago. I as only running the external filter so i put the internal filter in last monday and it has not made any differnce. I have ordered a small air pump, air line and air stone for my ornament to see if it helps and for a bit o effect. Does anyone have any suggestions of how to make the water any clearer?

thanks, Matty

I have a powerhead in one tank, are they better placed slightly above the surface ?

When my water was cloudy I used a carbon filter overnight and it did the trick.

 

[Matthew_gowland]

it has a carbon filter in both filters and no change

I doesn't matter that much, I prefer slightly under the water so I don't have to listen to the splashing. As long as the surface is moving, you are fine.
