Need advice regarding aeration..

[ijalabdullah]

Hi bros. .

Need some advice on this coz I do not want to misinterpret what I've read online..

I recently changed to a overhead trickle filter (wet/dry filter). Water output is as shown in pic.. as I feel that the output seems strong enough and there's a lot of surface agitation frm the bubbles, I removed my air stones (previously had 2 of those) from the tank.

I read that air stones dun really serve much of a purpose apart frm decoration and trickle filter or wet/dry filter oxygenates water quite a bit, that's when I decided to remove the air stones.

Am I doing this correctly? I do not want to suffocate my fishes. They've nt been gulping for air at the surface and seems fine. Just that i notice they're nt as active as before. But I did not see them going to the surface to gulp for air.

Pls do advice.. really need to know and learn.. thanks!!!

Apologies for the wrong orientation of the pic. Should be tilted to the right..

Anyways the output nozzle is below water surface as shown in the pic..

I think you should be ok with what you have. I use a Marineland Tidepool 2 sump on my 125. The water falls through 3 media trays and then over the large bio-wheel, which provides all the oxygen my tank needs. I use no other aeration in this tank. I did used to have a sponge filter in the sump that I could pull for emergency quarantine use, but that's been out of the tank for 4 months or so. Have never had a problem.

Only reason I could possibly see you needing more is if you had a warm-water tank, such as for Discus. The warmer the water, the less oxygen it can carry, and so you need additional aeration to support it.
