Can you ever have too much air in the tank??

[tintin]

Sorry if this is a really stupid question but Im in the process of upgrading a little bitty 20 litre tank to a 60 litre with a Fluval 2plus filter.

The Fluval really chucks out the air so theres always small bubbles travelling around the tank. I think it looks cool but is there such a thing as a correct setting for my fish? Can you have too much air going into the tank?

With regard to the blue flow adjudtser switch what setting do other Fluval 2 owners have it on? (mines currently on max but no fish in the tank for another week.)

I don't think so. It is possible to have too much currant, but having an excess of air isn't a problem.

I have a Fluval 2+ running in my 15g tank and it's set to about 1/2. This is beacuse i have GSP in there and if the currents too fast they shoot around like ballons in a storm
I also have the T-piece attached to airate the water and try and set it so that there's bubbles on the surface but not in the water. Bubbles in the water don't do much, it's the bubbles on the surface that benefit the tank as they increase the surface area of the tank and boost o2 levels.

I have that filter...it doesn't make any bubbles at all, except for a few minutes, when I turn it back on after a water change.

I have the blue flow adjuster whatnot in the middle. I don't want it at the lowest setting because obviously i prefer more water to go through...and I don't have it at the highest cos my tetras aren't fond of the strong current.

You can over saturate water with oxygen which leads to a condition known as gas bubble disease but this is not caused by the addition of oxygen supplied from filters and airpumps.

 

[clutterydrawer]

how does it happen, then?

 

[CFC]

Over saturation gennerally only occurs in planted tanks or those with a lot of algea growth which recieve direct sunlight and have little water movement. When exposed to strong lighting plants use co2 quicker and release a lot more oxygen into the water, the oxygen is created faster than it can be exchanged at the surface and the water and fishes blood becomes over saturated, this is noticable by hundreds of tiny air bubbles clinging to the surfaces within the tank. The trouble comes when the excess oxygen in the blood tries to escape and takes whichever the quickest path is out of the fish resulting in large blisters forming under the skin and if the problem is not corrected immeidietly will result in death.

Thanks For some reason I like to know such things "just in case"

I would think that the only way that you could have to much air in the tank is if you have NO water in the tank.

Thanks for the advice and info everybody.

Sorry for all the questions...but while we're on the topic...is tehre an "optimum saturation", as such? like in % ?

The outlet on the fluval should have a small hole on top which in your case is plugged (hence no bubbles). They come with an insert for the hole which is meant to stick out over the surface and allows air to be pulled in by the water.

I plug mine since its SO LOUD with the bubbles. I have plenty of air stones for bubles

I thought about using mine but will it do any good?

The aggitator adaptor (little T-piece thingy) is actually quite good. It creates bubbles which shoot along the surface with the current so it's increasing surface area not pretty bubbles, ie. doing something beneficial

It can sound like a 4-year old sucking the dregs of a milkshake through a straw though

Should I use it then?
