I have a bigger system - 750g display part of a 1500g system. The slew of hobbyist roller mats just wasn't a cost effective option to handle a true 4000gph flow back from the different tanks.
I was impressed when I was visiting Unique Corals and saw them using the MRC Roller Mat on their giant coral raceways. It was a big unit - about the size of a 15g tank. So you need a sizeable sump to hold it. But it's rated at 5000gph+ of flow.
I ordered one and installed it back in September. It's been a great add on to the system. The first filter roll lasted 6 months! During that 6 months I had to remove the filter roll 2x and reseat the uptake roll. But other than that it was 6 months of maintenance free clear water.
I have outdoor frag tanks and when I algae wipe the glass it dumps a lot of crap into the water column. But the filter mat just pulls it out and keeps the system looking clean and clear.
