I see lots of people have frag tanks. My question is why? Is it trading stock for other reefers? Can you make enough money to justify the cost of lighting and replacement bulbs ($65 per year for a MH plus startup ballast and reflector costs). Do you have it plumbed into your main system, thereby negating the need for separate filtration, or is it separate so you can also use it as a QT for new corals, or is it separate for some other reason?
