Submersive or attachable filter?

[Mr Fish]

Right now I've got a Fluval 404 for my 125 gallon tank. That filter is decent (quiet, too) but it's really only made for 65g-100g. I have the intake set up on the right side of the tank and the out-take on the right and middle (got a system.. forget the name, but I got to peice together the intake and outtake).

I've noticed on the left side of the tank there is more than I'm happy with amount of detrius and crud that will stir up when my bristlenose pleco zooms around. He does it quite a bit, he's very authorative.

I'd like to get a small set up on the right side of the tank to help with filtration and to help clean up extra detrius, uneated food and other crud.

However, my lids are pretty set. I don't have much, if any, space on the left to hang a filter on the top of the tank. There is room, of course, on that side of the tank but I'd like something that just suctions easily to the side itself and doesn't hang over the top (and require me to cut or retrofit my glass top to fit it...) Is there any kind of filter that easily attaches to the sides or can be placed under the water line? I don't think I'll have a problem making room for the power cord for a new filter, but that might be just about it.

I would say most of my filtration needs are being met atm, so I wouldn't need anything super powerful. Even something only made for 30-60 gallons would probably do the trick.. maybe even something weaker than that...

Thanks!

A powerhead with a sponge filter attachment would work well. They are very quiet, and while they won't carry the full load, it would help with capturing solid wastes. They can be a PITB to clean, so make sure you will have easy access to it. You'll probably need to clean the media every other week or so--more often would be better.

Eheim makes the Aquaball line of internal filters currently, they are very versatile but less than perfectly user-friendly (in other words, I liked the prior, now discontinued, line better).

Fluval also makes a line of internals, but I am not very impressed with them either. If forced to one or the other, I'd select the Eheim for myself, but either is worth checking out for local availability.

What about adding another 404, or smaller, Fluval, since you're already familiar with how they're put together? I have two 404s on my 125g, although it's acrylic, so I'm limited to where they go so both input and output for both are on one side of the tank.

i think you should vacum your tank more often so there isn't so much crud

are you doing water changes?

Fluval is making some nice internal filters....I got one for my 10. Maybe one of these..rates for a higher volume...in the corner? Or upgrade your filter entorely for one rated for your tank.

how about just a power head shooting current to move the crud to the filter intake?
