You 'could' but your AC70 is already more filter than you should really need, assuming you have the right media in there.
Good filtration/purification is not about pumping more water around, but finely filtering the water with media and products to remove impurities. And the best 'filtration' is actually the weekly water change to remove polluted water and dilute the rest.

Why do you think you need more filtration?

Agree with AD. You need to get another tank for the other filter

You all are so amazing just the idea of filters competing with each other is so insightful. I would naturally think about cooperation. I learn something here everyday.

I have two filters in my aquarium a 305 fluval and a ten gallon under gravel filter. I added the under gravel filter just for ole school comfort of seeing the bubbles rise. It never occurred to me the under ground filter would work and compete with the canister.

Can I keep both filter in operation without injury to the inhabitants?? I really enjoy watching the bubbles go up

Hey Pop - I too am old school. Under Gravel Filters (UGF) are economic and can be great bio-filters... but do so with some risk. A lot of waste material, including uneaten food, gets pulled down under and decomposes. This can result in a real nitrate producing mess if the gravel isn't routinely vacuumed (gravel siphon) to keep clean. Additionally, if there was to be a power failure or a problem with the air pump, anaerobic heterotrophic bacteria can produce a foul mess with some nasty gases.

I used UGF's in the past, but don't anymore. I find that sand is a much better substrate than gravel because all of the detritus/mulm stays on the surface where it slowly decays or is easily removed during weekly water changes. And there's never any uneaten food that gets away from the stock.

You can continue to use the UGF - you have to unless you tear the tank down as you can't just stop the air/water movement w/o risk.

If you just want bubbles, go with a bubble bar - they look really cool, especially when one whole side of an aquarium has a bubble wall.

Agree with Abby's dad regarding the AC70 for roughly 35 gal tank.
But finely filtering the water, only work's well for small tropical's and would not be the way forward with large waste producing fish, or heavily stocked tank's (been there ,done it).
Is near impossible to over filter a tank, but easy to underfilter.

I guess it depends on exactly how we define filtration...but we'd need another thread for the great debate.
