I would like to put very small Fluval Bio Rings in this. I'm just wondering will they fit? I can't find a picture of the inside of this cartridge.

I am sure they would, but I don't know size of those rings, I have put Sachem Matrix Carbon in these and they fit and worked just fine. Good Luck

By itself I don't believe it's suitable because it has a strong filter, however if you do what I did it's suitable, I have two FLUVAL tanks with a betta each , and I have no problems, both are cycled and work well. What I did was I took a black filter sponge about two inches square ( you can by them at a fish store , you don't need to cut from the ones that come with the tank) and I pocked a whole in it , about an inch through ( not all the way through) then i inserted the tip of the white tube that is connected to the filter, I tied the tube to the back side grid tank ( wher the biological media is located ) It has helped slow down the flow and my bettas are happy and thriving.

Jim, I use one of the units and love it. It has a small tray to keep things off the bottom but the inside is stainless, your cartridges would work fine.

I replaced the filter with a fluval filter. Yeah, it was strong and dangerous in my opinion. I just sold this tank! It is an awesome tank! More on the fluval mini filter, you can adjust the current. Make sure you can return it because I have found some models of the filter to be noisy.

I have one mounted concealed from view in the filter/pump compartment of a Fluval Spec III (2.6 gal) and it works flawlessly. Should be fine in a 4 gallon. It's large, but it's flat.

I used them in a Pentair Clean and Clear plus. Its a 4 cartridge system. Check your dimensions 20-1/6-by-3-by-3-inches

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. I have it in a 1.5 gal glo fish tank.

It looks like it would only fit on the side, and that would greatly detract from the looks of the aquarium, plus you have a built in filter, so that function would be overkill. I would look for a in tank UV light, or a different aquarium option.

You can use any filter media you like with these marina filters - not just the cartridges. If it is loose media, I would recommend using a net bag or a bit of panty-hose to keep the bits from coming loose and getting into you tank.

I'm also having this issue. None of the filters here on Amazon seem to be the requisite (approximately) 6-3/4 diameter that would work. Right now I'm thinking I'll buy this larger size Counter Composter Replacement Filters: Large 2 Gallon, and cut it down to the correct size. It may be something that could be purchased elsewhere, but I'm just not finding it on Amazon. It is more than a bit frustrating!

I ordered the "SunSun 3-Pack PLUS Coarse Fine Filter Pad for Aquatop CF300 and SunSun HW302 Canister Filters". I can report that while the major dimensions of these pads are compatible, they are obviously made for a different canister filter. The hole is smaller and in the wrong place. You can flip them them any which way and it will not help. If you tried to cut them to fit, the original hole will be about 80% intact and allowing the flow to bypass the filtration. These might work in a pinch but they are not the correct filter.

The Fluval filters have grey, plastic cartridges. It goes into the bottom one.

I have it in chamber 2 in my 29g biocube... I have plenty of room, you should be ok

Not sure it was intended to be used in a pump basket, and not sure if it would fit. You don't necessarily have to "assemble" the cartridge as depicted in the picture but even so the 4 individual cartridges are each 6-8" long. If your basket is smaller than that size, then they won't fit.

No it should not be dropping into a tank. Those bio rings acts like a natural filter for the water And your water in the tank does not flow like a river so it will not work efficiently to filter out harmful stuff. Is recommended to be placed in water filter for best result

Kind ofyou need to cut it down on the long edge about half an inch to get it to fit. Cut 1/2in off long edge and place both filter in cartridge at same time or oder the ones K. Ashurex suggested :-)

I bought this for a 5 gallon Fluval Spec and it works great. Very easy to use and makes water changes easy. Should work for you.
