There are single sponge and dual-sponge units, in different sizes too for small to large tanks, this one is rated for 30g, mine is on my 29g, and the smaller on the 20g.

I use an air pump. Also an Elite as it happens, I've had a 801 I think it is for almost 15 years, never a problem. So when I hooked up 3 tanks with sponge filters last month, I bought a larger Elite. They are not expensive, I'm in Canada and I got the new one at Petsmart for $19 (will be cheaper in USA).

I can't have powerheads in these tanks, the poor fish would be buffeted all over the place, and these tanks have very small fish that are wild caught in standing water mainly.

Thanks Byron, The tank will be housing Dwarf puffers. So with that said maybe it would be better to run it off a air pump. Less current that way. Will that be okay will the plants in the tank?Will running that filter off of an air pump cause to much water disturbance?

No (on the water disturbance). I position the top of the stem just at or below the water surface so I get a gentle "push" of water away from the stem, but the water does not ripple. Even if it did, this is minimal.

Dwarf puffers will be ecstatic in such a setup. Mine was.

Did you think about a baffle for your AC50 ? Sponge filters are fine but a baffle made from a water bottle just might solve yer problem ?

I finally got in my sponge filters that I ordered for my 10 and 29 gallon tanks. I got the double running in my 29 gall and it seems to be okay. The single I could not seem to get to run right? I had both running off the same air pump that has two outlets. Not sure if it was too much are for the single or not enough? I disconnected it and left the double running. Here is a pic and a video of the sponges and air pump.
That air pump is one I have had for a long time and haven't used.

Before I left for work I made some adjustments to the single one and it started running a little better but still no where like the double any suggestion? One my way home tonight I think I am going to stop and pick up a small air pump just for that 10 gallon and see if hat will work better.

you can't usually run two lines off one air pump unless you have flow control for each line. Without a valve on each line the air will mostly take the path of least resistance. This seems to be the 29gallon... it could work, but you need to make sure the resistance in both lines is about equal or adjust it to whatever flow you want... this may mean moving the pump so one line is shorter, or moving the big sponge filter down further(so it is deeper), likewise moving the single one up should help it.

What kind of valve are you talking about is it something I can go buy? or something I have to make. I was thinking it was just not going to work like I had it but wasn't sure why? I didn't really think about the air taken the path of least resistance. That makes sense though. If I can buy these valves how do I place them on the air line? I guess I am asking where to place them at?

Also How long do I need to let both filters run before I can take out the Aquaclear50 out? I was thinking I need to let both run for a couple of weeks? Is my thinking correct?

Mikaila is quite correct. Buy yourself a single stem air pump, I have the Elite 803 running 3 sponge filters on a 10g, 20g and 29g and it is fine. I had an Elite 801 (think that's the number) and it ran two very well. The 803 new was only $19.00 in Canada at Petsmart, will be less in the US.

Then get a valve with two outlets (or 3 for good measure). The plastic ones work but are harder to adjust I find. The brass are better, more expensive. up to you. Then you can adjust the flow. It is also good to always have two flows anyway, even with one filter, so the pump can run at max. Run a piece of tubing from the air pump nozzle to the valve unit, a few inches is fine, then the airline from each valve to the respective filter.

Yes, a couple weeks is fine for the two filters.
