Canister filter for vivarium?
What kind of canister filter would you recommend for a vivarium water feature? This tank is 21in tall, so the tubing would have to be pretty long, and I'm not sure if you can extend them without reducing the flow (although I'm assuming that if both are equal lengths the flow would be balanced). Because the water feature is to be small, the filter doesn't have to be very large or high powered. However, it should be able to handle a considerable amount of dirt particles (which would inevitably be dragged into the pool by my tiger salamanders.
