Reef Tank Roller Mat 2 Month Review - Bubble Magus Filter Roller 

I've been running the Bubble Magus roller mat in my 200 gallon saltwater reef tank for the past 2 months. I needed a somewhat compact roller mat that I could modify to accept dual 1-inch overflows. The Bubble Magus has exceeded my expectations and it's much less expensive than the roller mat systems I was originally considering.
