airation

[tom M]

I have a filter on the back of the tank , do i also need a pump and
something giving more air? 20 gal tank

[Brian S.]

Depends on the amount of fish in the tank.

Do you have a 20 long tank?

Either way really, if you have the over-the-back filter, this should provide
enough agitation for the water to provide sufficient oxygen disolving into
the water.

If you have a hang on the back external filter, you typically don't
need any more aeration as this will break the surface of the water
with the water return.

I have power filters on my 5 tanks, but I enjoy aireation. Also I
position my heaters in the air flow to move the heated water faster.
Air is especially helpful if you have to treat the water. Some
medication absorb oxygen and will recommend air be added if the fish
stay around the top. (I think RidIch is one). Also, dense fish
populations may need extra air.

I have seen many fish swim up and down in the colums and Plecos lay on
top of the stone. Altogether, I think adding air is good for a tank.

It is my understanding that aeration does not do much if you already
have something that is causing ripples on the water surface. You may
want to consider whether you want the noise from an air pump. I read
that unless you want to spend couple of hundred dollars on a linear
drive (I think) air pump, you WILL get a noisy pump.

Observe your fish, if they look fine, they are fine.

I have found Rena air pumps to be amazingly quiet. There are three
running within 12 feet of my desk, and I can't hear them over the
power-supply fan in my Dell.<g>

All 5 of my tanks have air. I find it easy to ignore the sound of the
pumps. My power filters make noise as well. During the day I have
two computers running, then there is the refrigerator air conditioner
or furnace. Low level noise is just masked out.

I understand the air is not always necessary. I like the bubbles, the
fish don't mind and it is assuring to know I am doing what I can to
keep the oxygen level up. My tanks are densely populated. I am
surprised you don't enjoy the bubbles.

Maybe that says more about Dell computers than air pumps ;-)

Hang your airpump on a string so it can't vibrate against a surface
and most of your noise goes away

I built a box with PC soundproofing foam and hung 2 air pumps in it
I put the open side against the wall and now I can't hear the pumps
at all

Or....buy some ear plugs

I've got my air pump on a timer to go on when the lights go off.

It is all relative. That is why in one of my other posts I used the
Fluval + internal filter as a reference. Compared to the Fluval +, my
Rena is very noisy

One note here: Photosynthesis DOES NOT stop at night, it merely focuses
on other parts of related biochemical cycles. There's much much much
more to making sugar from light than splitting water using excited
electrons.

Well, what the original poster was trying to say was that the plants
were not supplementing the oxygen supply at night. So, whether
photosynthesis stopped or not was immaterial. Of course if you can
prove that oxygen is produced at the same rate in the dark as it is
during the day, then you have made a relevant post.
