How to stop air pump bubble from spreading out of the tank?

[doubleace]

Hi Guys

Anyone know how to solve it? I am using air pump on my tank and sometime I can see my floor is wet. How to prevent the water from spreading out?

Thanks

[flybaits]

possible to minimise the pump flow? or use air stone?
a good air stone should diffuse the air better thus finer bubbles. n the tank water level may be lowered to a suitable height.

try playing with all this n see which one suit ya.

cheers!

ok thanks..

[flybaits]

no prob.

cheers!

Hi,
use a simple airlift pump instead of a normal airstone. Something like this:



Install it at the tank wall with a sucker. The top should be half submerged. The bubbles will gather themselves in the top and at the end of the tube just the air and a slow water current will leave it. This way no water will splash outside of your tank. It works best with a diameter of 0.5-1".

Robert,
what do you mean? Attach the pipe to the inlet of the canister? Or just a pipe itself? Can i just use those stick on the wall sponge filter?

I don't like the splashing caused by the bubbles too. Not using a airstone/diffuser seems to solve it.

ck,
but my setup do not have any plants in it.. so i'm using airstone to produce oxygen for the fishes..

[CK Yeo]

Yes. I mean do not attach a air stone to the hose.

oh... you mean just the tube itself no airstone nothing..

ck,
Thanks problem solved...

No plants? Means light not so crucial. Why not just put a cover above the area where the bubbles are? You don't need to cover everything, just the corner.

vinz,
ya no plants.. i thinking of putting a stylofoam above same as what C328 do to their crs tank and after CK had give me the idea of removing the airstone and it solve the problem and it also increase the movement on the water surface.

change your airstone to those air bubbles reducer it work like releasing the bubbles in micro sizes, when it reaches the surface of the water it creates less movement.

bubble reducer? Any picture or link? Anyway i already remove the air stone and the water no more splitting out of the tank. And it also create movement on the surface very good..

wooden air stone or a tube-like create O2 rainbar may do also

I have got a Hydor aerator that switches on at night, and my tank is covered with a DIY canopy. For a period of time, I saw water beneath the tank in the morning, and water level drops faster at night then in the day when lights and fans were switched on, which made no sense. In the end found out that the air bubbles created by the aerator bursting at the water surface splashes some water to the inner side of the tank canopy, and it flows down between the gap of the canopy and tank, down to under the tank.

My solution was to paste a piece of plastic sheet on the canopy, to allow the water to flow back down into the tank, instead of the gap down my tank. So far it solved the problem, though water still splashes onto my light sets' reflectors casuing stains. =(
