Hello everyone,
I would like to get people's advice on this item I saw on eBay. It is a refugium kit to convert a standard 10 gallon tank. I happen to have a spare 10g, so I got interested.

I would like to place a refugium over the main tank. But I've never set one up before and I have plumbing questions. Such as:
1. Using the kit above, how does water get back to the main display. Naturally, I would prefer it to be gravity but I don't think that is going to be possible with that setup.
2. If it is fed back to the main display using a pump, what kind of pump should I use?
3. How do you balance the flow between the input and output if there are 2 pumps?
4. If it isn't 2 pumps, and some sort of siphon is taking place...what happens if the pump fails or the siphon is interrupted?
Thanks for any info!
