Can this filter operate totally submerged? I have an aerator (bubbler) so I don't need the filter to aerate the aquarium. Thank you for your answers, now I have another question... If I have the waterline up to the lip of the filter, how noisy is it?

This filter wouldn't work totally submerged--the water would flow out the top without passing through the filter media--but it doesn't function as an aerator. It only makes bubbles when the water level in the tank is low.

You need to replace the oxygen for the fish to breathe that is what it does. Not all fish breath through guills so you need to know if any of your fish do. Some kinds of filter systems do provide some oxygen but I still prefer the air pump.

The water will not circulate through the filter it there is no power. It stuts down every 12 hours for approximately 1 min to purge any air. This is automatic. However if the canister is set lower then the water in the tank it will fill with siphon once it starts. It is by far the best filter pump combo I have ever had and would highly recommend. I love it just plug it in and forget it.

I had this filter for a five gallon tank as a secondary filter. Mine started making noise as well, so I changed the filter. I did find that the lower it was in the wate::r the less noise it made. However the noise eventually got worse and became annoying, no matter what I tried! It may be better for 3 gallons or less. But I was dissatisfied with it. I hope this helps!

I don't think it has to be submerged. What I think it means is that pump will work when water reaches a certain level.If it empties your tank is working OK.

Hello. The filter will start making a gurgling noise when you need to change it. They are small and seem to need changing frequently. If it is a new filter you also may want to add water to tank to stop the noise. Filter should slide in the grooves and all the way down. I don't think it's suppose to be partially pulled out

I don't know how taking air out (of what?) would make any difference. It is very noisy but that's due to the design of the "waterfall catch". It's not broad enough to make the water cascade slow/wide enough to be quiet. We mute it by putting a small bowl that fits just over the top of the ledge and rests on the bottom of the fountain. It cuts the sound way down.

No. It was way too feeble for my 50,000 gal pond system, but I don't think it is possible to have too much aeration. As someone else mentioned, you can always hook up extra air stones.

No, this model does not require a filter to operate. A filter can be placed within the tank to prevent calcium build up if needed though,

My pond is about 800 gals and this unit is good for aeration not filtration. You need to also add a good volume pump and separate filter unit.

Yes, the filter can go all the way under the water. And the flow can be directed which way to go. The extension wand is very nice. My Betta doesn't get thrown around. And you can set it to high or low.

the bubbler itself gives plenty of bubbles. I used them for a move of my 60 gallon aquarium. As to how much it can handle depends on the amount of fish you have in there and the amount of water 1 bubbler easily oxygenate 5 gallons of water, and in that small amount of water I defused them to tone down the flurry of bubbles. I was very pleased with battery consumption and they are pretty quiet.

So most everyone sees these bubbles as a problem? I miss them having switched from a pair of simple power filters. I have the eHeim intake on one end of the tank and the output dumping down into a bubble wand for a long strand of lots of bubbles. The fish - tetras, mollies, platys, loahces - tend to congregate on the intake side of the tank. Not cool?

Have not used the other devices you reference. The PF40-UV is not loud but definitively not what I would call quiet, especially when the strainer or tubes get a bit clogged or the skimmer doesn't work correctly.

Our tank less makes no noise at all. I installed the unite my self just under the bathroom floor. In the year we have used it I replaced the scale filter 2 months ago. We don't have soft water so it gets a real work out. Other than that we have hot water in 15 sec after we turn it on no noise just hot water.

I think you will be happy with this filter. I am using one in my 200 gal fish tank I like it because 1. it is a good filter 2. It keeps the water oxygenated. ( lot's of bubbles ) :-) when I get my 75 gal tank ready I all ready have one for it.

Maybe some fluid engineer could comment on this, but if you can pull water up a short tube that means water is being pulled through the filter. I have a 6 inch tube in an aquarium and that functions well.
