What do you think of this idea??

So you want your Q-tank hooked up to your main system to double as a refugium? The big issue I see is that the whole point of the quarantine tank is that it's physically seperated from the display. You may as well put fish directly in the display if your hooked up.

That being said, I wonder if you had it hooked up with a uv sterilizer on the return if it would work. You wouldn't get any pod's out of the refugium but it would be a good place to grow algae.

No im not having it hooked up to the main system at all its going to be seperate but im gona fil it abou 50% of the quarantine tank with water from my main tank.

...How would it be a refugium if it's separate from the main tank?

I think it would be easier to just make 2 seperate tanks. one for your Q and the other as a fuge.
