I may look into those filters. I've tried adding small internal filters and powerheads to increase flow in my 20L, but it never works out due to bad suction cups, rattling impellers, etc.

Not many. I have 7 danios, 2 amanos and a mystery snail who would all move to the new tank. I don't stock very heavily

Hi everyone. I have a 20 gallon long that has been running for 2 years on a medium co-op sponge filter. I am considering moving up to a 29 gallon and I'm wondering if a single medium sponge will still be adequate. Is anybody else running that setup or have any experience doing so? I would like to avoid motorized pumps if possible. Thanks.

If your tank is close to the wall, you can mount it to the wall above the tank using shelf brackets. You can either support the light with the brackets themselves, or put up a shelf and mount the light on the underside. I have mine set up this way but its a little work and once you do it you can't just move the tank around.
