It sounds almost as if the impeller is riding loose... is there a pin in the bottom that holds it centered... or was there? Cheaper to buy a new impeller, if you can get parts, than replacing the filter even if a canister would be nice it's still costs more.

Well, I'm making my canister filter. To build, the cost is going to be around $15. The only spendy parts will be the pump and some more ceramic media. Hubby's not very keen with something else that houses water going onto the carpet. But nothing an old kitty litter bucket can't fix ;)

Today, the filter is very quiet. But that doesn't mean I have reconsidered ditching it. I'm not going through that grinding again :P

Make sure you post some pics of the filter when you are done... I love some of the DIY inventiveness.

You know, you probably don't need the ceramics. A sponge will supply as much surface area as the ceramic will. The apparent advantage of the ceramic media is that it is able to house more benficial bacteria... which it may do, I certainly won't argue that point. The issue is that with the fine pores, the water needs to be under pressure to pass through the media to enable it to pass all these organisms... it can't do that in any typical aquarium filter. All the water does is pass around the tubes, rings or chips and contacts only the surface areas of the pieces, not the internal surface areas of the fine pores. The exception would be a ceramic piece that has larger pores to allow water to flow at much reduced pressures that the filter may provide.... which is about the same as a fine pored sponge or floss material.

With plants, even if this sort of media did what everyone seems to think it might, it is redundant anyway as there are tons of surfaces colonized without needing to worry about adding more.

Help with Flourescent Lighting

Sorry guys!

Well, I was gonna do this method: HOW TO: DIY Canister Filter - YouTube
It would be 2 ft tall. So if I did it all sponge, it maybe difficult to access those at the bottom to rinse when needed.
But if I CAN do all sponge, it would reduce costs quite a bit. My tank is also not completely stocked. I do expect to get atleast 2-3 other species, each needing a school of their own. 3 upside down cats for hubby, atleast 6 cory cats, still searching for those striped kuhlis since my lone striped guy won't bond with the brown kuhlis i got. And lastly, possibly a school of tetras or barbs to add some striking color to a mostly black/white crowd of fish.

Sponges are largely comprised of open space, which bacteria cannot live on. That's one of the characteristics of a sponge. The denser the sponge, the better.

marineland hof

I just bought the marineland hof today, I have sand substrates and did not shut off my filter when cleaning my tank, needless to say the top fin hof died, I tried everything to clean out the sand, anyway, do you like the marineland? I have the 350, I love the idea of the bio-wheel.

its been great, until the grinding that it started up on.
I believe your top fin filter is supposed to have a lifetime warranty. You could just traded it in for another top fin.

Water does not have to pass through all of porous media in order to be effective. Live rock in SW teaches us this. Sponge material can be effective but as Jaysee points out, needs to be finer/denser foam than most sponges used. As a matter of fact, the Aquaripure denitrate filter is completely sponge with 4 different densities of sponge, coarse to very fine (although it should be noted that the output of this filter is a drip). I think there is merit in enhancing the bio-filter capacity with it's ability to purify water. And don't sell the ceramic and related type medias short.
However, I tend to believe that bio-filtration works best when the water flow is slower and the colony is not disturbed. This is difficult to do in most filters that include mechanical filtration and higher flow rates.
