the instructions that came with the tank/filter said to fill it till its about an inch below the filter output. It's an external canister. I guess it just depends on how full you want the tank, and what your filter needs. If raising the level of water higher than that one inch slows the current downn then it can't be bad. I just like to hear the gurgling, it's relaxing and I know its working.

i fill mine to about 1 inch below the top of the glass... both are above filter outputs,

i used to find the sound of running / splashing water relaxing too, that was until i kept my 9" golden nugget in a bucket, while i was making a diy background in the tank, i kept waking up to him splashing about and freaking out cos i thought he was / had jumped out! NOW it stresses me lol

yes, fallout, but the air is a lot more humid there year-round than most places we live and keep our tanks.

It is also very important for fry of labyrinth fishes to get their first breath of air that is warm... anyhoo...

I fill my glass tanks to the beginning of the plastic rim part. The acrylic tank is filled to about 3/4" from the top because it has built-in supports and the light sits right in that, and we don't want all that stuff hanging in the water

I always heard that with fish who gulp air frequently, you need more humid air to collect under the cover

Makes sense, but think of the wild... there is no plastic cover over the river...

Hi,
I keep my tank(s) filled to the beginning of the plastic
trim.

I like to fill my tanks upto the rim/ just under the spraybar. It looks alot better and there is less noise

OK, with my last water change I raised the water lavel to just below the output, and what a difference it made. There is much less current, and that gurgling sound is gone. Wife really liked that part.

I keep gouramis and cories, so I keep the water a little lower than the filter. I always heard that with fish who gulp air frequently, you need more humid air to collect under the cover, so they are breathing close to the same temp they are swimming in. Anyone else ever heard that?

Thank you for that reply. I was just checking on my facts I thought I had all the correct answers. I am never to old to learn.

In a planted tank the more surface agitation you have the less CO2 in the water. The increased agitation disrupts the CO2 that usually collects around plants. As you are aware alot of peopl add CO2 to their tanks to get better results. Very little agitation should be utilized regardless of the addition of CO2, especially so with the addition.

In an overstocked tank you have more absorbtion of the O2 in the water. Tanks with a small surface area and little agitation often run into problems with the amount of O2 in the water (your fish are making alot of trips to the surface to gulp air, and in some cases death).

Typically planted tanks are not overstocked as too many fish will usually result in damaged plants.

Plants can live on either O2 or CO2 however the more CO2 that is available to your plants the better results you will get.

Could you or any one please explain exactly what you mean by the following statements.

If its a planted tank you want as little surface agitation as possible ..

If its overstocked youll want more agitation so that you are getting more o2 into the water.

Would this only apply if you are using Co2?

My tank is extremly heaverly planted and possibly stocked to the limit but I have plenty of filtration/airration to cope with all that. I do not have Co2

My aggitation is caused by two risers from the UGF each has its own pump and puts out a lot of water mvement, also two 4ins fine airstones again each own pump. All this movement is at the rear of the tank.

The outlet from the large canister is released and angularer directed just below the surface.

I actually prefer the soud of running water it is very relaxing furthermore you can hear if any problems are about to start.

If its a planted tank you want as little surface agitation as possible .. so the higher the better. If its overstocked youll want more agitation so that you are getting more o2 into the water. Personally the sound of falling water bothers me so i keep all but my turtle tank filled to about 1/2 inch below the very top. Of course most of my tanks are planted so that does double duty.

Do you have to fill your tank to the top? Or do you leave and inch or two off?

I like to fill mine right to the rim......and then jump right in the tank, and splash around in it.

Alright.....I'm being silly.

I fill mine to just above the bottom edge of the black border/seal.

I fill to cover the outlet bar from the canister filter which is less than one inch from the top, it is also just below the tank struts that support the glass top. This also reduces the noise level. It is a matter of choice and will depend on the filtration system you use.

I fill mine just a bit above wear my canopy sits on the tank, so 1-2 inches from the acutal top of the glass.

I also fill my tanks to the bottom of the top trim piece. As stated before, if the water is any lower, the bio-wheel filters will cause a lot of spashing noise. With my Whisper filter, it doesn't even matter. Even an inch below the rim and there is no excess noise.

I like to fill mine to at least where the black seal and glass meet...of course it's usually a little more than that...

Thats what I think too. I want to make the current slower so that helps. And it does look nicer!

I fill it to the rim (the inside rim, of course, not the absolute top of the tank!), otherwise the Emporers tend to cause very little surface agitation. When filled to the rim (which looks a lot nicer, too, of course) the output sweeps right across the surface, perfectly.
