I just bought one of these and need to know how to put it in the tank. Have always had the ones that hang on the outside of the tank. Have a huge aquaclear filter but it kills my fish. It sucks them close to the tube and kills them. So I bought a 40...

The suction cup adheres to the inside of the tank and sits at about the water line. The cord goes up, away from the tank water. Your filter fits in the slot where the water goes through

I have only had my tank set up for a little over a month. It has one betta in it. Yesterday the filter died. Can't get it going again. I had to go out and buy a new filter to keep my fish happy. Now I have to find a light that will fit on the tank so I can get rid of that huge useless cube out of the middle.

Hi Edward, I have the big filter series that take two filters. I use it for a fifty gallon rubbr stock tank I keep in the basement to keep giant goldfish brought in from the winter. I keeps the tank clean as there are 8 really big goldfish. I usually pull out the two filters about every three weeks or so. I also take out the whole unit and clean out the scum from the unit, So-- 3 into 52 weeks in a year-- 17 or 18 times. These are messy fish, so maybe I change them more often than I need. Hope that helps.

I used the Tetra filter in a 20-gal tank when my yellow-bellied slider was a hatchling for about the first year, but when he got to about 8 inches I had to switch to a larger (75 gal) pond so the only thing that can handle that is the Aquaclear 70 Power Filter I now use. Much less work in keeping the water clear and he loves the swimming space.

You need to replace the sponges IMMEDIATELY with a better filter medium. Look through the reviews and you will find what to use. Otherwise this is a great, quiet little filter for very small aquariums.

You did nothing wrong. The filters suck. You would have to run them for days until they clear out. I gave up. Glad it was cheep. I went to Petco and bought a Tetra whisper in-tank Filter. Cost a little more but works just fine.

I got a 50w hydor heater and placed it in the tank. But its only because my betta couldn't swim well with the filter not modified. If you dont lower the water flow you can put in inside where the water pump is

I just attended a seminar from the guys that do the show "Tanked" on Animal Planet. They recommend (if additional filtration is needed) an outside filter that sits adjacent to the tank. These supposedly provide much more thorough filtration than an in-tank system, and dramatically cut down on the biomass debris from food that can cause algae bloom and fish kills.

But HOW??? None of these things open up, and you can't reach around corners with sponges or hands through these tiny openings. Can someone please explain this to me? Is it a design flaw with literally ALL humidifiers or am I missing something? How do you get into the damn tank to clean the brownish/pinkish sediment that begins to coat them?Thanks!Melissa

The filter mounts on the outside, only the intake tube and the output waterfall are in the tank. I use it for fish so I can't address it for frogs however I use Youtube quite a bit and hopefully this video might be of assistance:https://www.youtube.com/watch?v=JWiVQjZQNbA

It should work ok for a 30G tank. I have it on a 27G tank. It's rather weak even with almost no media in the treys. If you have saltwater tank with corals that need some current, this is too week. I know it's rated for much larger tank, but it's grossly overrated. I just got this too:( I'm really regretting it. It's unfortunate, but a powerhead will be needed for me:(Just to be clear, even if you have a fresh water tank, you liken't can't get enough flow to filter the whole tank with this power. Go up a model or 2 and get more power. Other than the lack of power, I do like this unit. I just wish that they have marketed it with the right GPH, and that I have purchased a more powerful one.

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.

Yes, absolutely you still need a filter. The airstones are beautiful and provide a bubble wall putting oxygen in the water. However, this does nothing to suck out feces and other things in the water to keep your tank clean. The size of your tank and the type of fish you have determine how much and what type of filter would be best. But yes, you still need filtration.

Mine went out in 2 months. Not good quality in the slightest. Replaced it and never looked back. Also a 20 gallon filter on a 25 gallon tank is probably too small if you fill it up all the way. You should always go bigger. But that's off topic. If it came with the setup then use it until it poops out and replace it. If you bought, return it. I can't speak for fluval but I know I hated the aqueon.

I have it in a 1.5 gal glo fish tank. It's a square, 7.5 " tank and the depth is a little under 7". The filter fits it perfectly. The filter that came with it was too small to be useful. This gets good flow and it is a cartridge filter system so they replace easily. I've had 2 of the tetra glo fish and a cory cat for about a year now. They do fine in the tank, I have a small plant in front of it to diffuse the intake some and the fish have been fine. In your question you asked about the half moon. That one I would not recommend due to the shape and space, but a square tank with the filter in either back corner should be fine.

Just drop it anywhere in the tank; not in the filter. This thing works in addition to the filter. Using both is great.

Yep, that's what I did. The filter tube took up too much of the tank for me. I removed the entire filter assembly (the below-gravel part, the middle tube) and just use a small side-mounted filter, which is more than sufficient.
