The image shows two stacked on top of eachother. How would this work? With a closed bottom, how would air/water would get in the second filter?

It wouldn't work. I saw that image also and it made no sense. Also, these filters arrived assembled in a different order than the images / documentation (incorrectly assembled, with the fine filter material "before" the course layer.) They were cheap, though.

I am only using the one in 10 GAL. Filter works purphict. My purchase was for the one only. This is a must have for breeding az I am using for Molly fry.

The Vertical Up position allows water from both 1 and 2 together. The Vertical Down position shuts off the water completely from both

There are two processes going on, a permanent filter in the front and two replaceable ones right behind that. Careful, they are sold in boxes of three so order two boxes to keep it even.

No. The rising/expanding air bubbles in the tube sucks water through the sponge filters. So, I would say you want the top of the tube no higher than the surface, so water actually pours out of the tube. (too high above the water, and possibly only air is expelled, and there is no filtering.) I suspect that the lower the tube is submerged under water (and the longer the tube is extended), the more water is drawn through the filter, and the cleaner your tank. But, one advantage of this kind of filter is that you can place the tube at the surface, and so limit how much the surface of the water is perturbed.

That's a puzzle to me, too. I use them both putting the square one in first, figuring the round one seals the lid to keep the odor inside the bucket. And, I'm guessing here... maybe you need both or maybe some buckets have a different configuration.(though I don't think so) I do have the larger compost bucket. Using both filters together works in my kitchen.

should have two stack. forgot how many in each one. i think around 350 filters on each stack.

I assumed it was just to double up on the filters. I put the square one in first and then the round one holds it in place.

The pre-filter goes in first. The main filter fits on top (pleated side facing downward).

The filter should be below the tank, as it works best as a gravitational suction system - but you could probably have it alongside the tank provided it is below the water level.

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.

They can't be used in unison, you use one or the other. Filters are usually fairly specific to what kind of filter they need. These fit in the under 5 gallon version of the Whisper filters.

I fill mine up, let it filter to the bottom and then top it off until totally full to the line at the lid. NO PROBLEM

I find the question hard to understand.The intake is through the slotted sides. That way the water passes through the filter, through the pump and out.

Hi.Need both, water for the bottom and air for the top. I used sand in the bottom

There are 2 large "filters" that water runs over, picking up moisture and is blown out the top. Right now I have the unit turned down about half way and it's putting a gal. and a half of water per day in the air. GREAT unit!!

It can if you stack the filters past 2. Otherwise I do not recall having this issue. Getting a filter holder that has smaller gaps between the filters can help allow up to 3 filters. These filters though are best to keep at two since they are not glass. This is to help keep as clear as possible picture.

We have a two story and it works fine, but would probably depend on placement. Ours is placed at the bottom of the stairs. We've had this unit two years now and it still works great. You do need to change the filter more often then stated in the manual and I would recommend a water treatment for the tank. Ours holder where the water is held gets slimy pretty quick without it.
