Gotta love getting nearly the pump specs for flow rate. I think that it what interested me in the OHF
Over-Tank Sump - Completed (pics)

- Start date
Am I missing something here?
Your bio media is not totally submerged? So if the power goes out surely your bacteria is going to die?

If the media were submerged during a power outage, it would run out of oxygen and die - this setup doesn't has that problem as the water will drain into the tank, and be exposed to the air. It would probably die after a few days however, due to drying out and being starved of food.
Nice work OP, very clean - I would have made it longer and flatter (like the flowerpot thread) however it's still well thought out and executed.
L C G - in this example, he's using bioballs in a trickle filter, which should not be submerged. They are most effective when the water is allowed to trickle over the eddies created by the surface of the bioballs. Other types of media are designed to work in a submerged capacity.
Intersting........I just learned something ;-)Clay;4285933; said:
I have a canister filter with bio balls in. What is the better option to use in a canister filter then?
Depends on the design, but typically, a mixture of media in layers. Mechanical then biological, then sometimes a water polisher or carbon.L~C~G;4286000; said:
I typically use eheim filters (love em), and go with ceramic rings for mechanical, then ehfistrate for biological. Bioballs are less than ideal for use in a canister, but they aren't doing any real harm.
Another option is to use several kinds of filtration allowing for ease of maintenance or carbon applications. You could use a w/d filter (above or below) and a canister to polish the water. The canister could be filled with mostly mechanical filtration to remove the particulate matter from the tank, and as needed, a bag of carbon could be added to it. The wet dry would be your primary biological filtration in this case, and the canister would be mainly responsible for making the tank crystal clear.
Sorry to derail

Thanks. Longer and flatter will be the one I build when I get a larger tank. After I buy a house (finally) I'm getting a 500g. Really want some aro's! Also, this is not a tank I made. I just recycled the old under-tank sump. IMO, the best DIY's are done through recycling what you already have.
I was thinking something like this from what has been talked about. Jesus I hate reading all these threads now I want to do that for my build as well.
