Efficient
Keep your gear working and money in your pocket. Giving your equipment the optimum enclosure is the best way to keep things as efficient as possible. MRC® knows success starts at the heart of your system’s filtration.
Adjustability
From water height adjustment to keep your skimmer performing at its best to Tank Saver Technology, MRC® has built flexibility in the form of adjustability in every xSeries™ Sump.
Tested
Every xSeries™ Sump goes through a rigorous check list to insure our strict tolerances are met. We like things to be right and right the first time around.
Detail
Entry level doesn’t mean the details have been overlooked, at MRC® we put the same level and care into the xSeries™ line of products as we do our +Series and, as always, they’re still 100% American made.
All the Right Things
The sump is the heart of your aquarium’s filtration system and with anything that has a good heart it must have good intentions. At MRC®, we believe that as your abilities grow as an aquarist so should your system.
xSeries™ Sump Systems come feature packed from the get go, giving you all the tools for success at a price that allows you to grow into our +Series or even iSeries filtration sumps.
Ample room for equipment, adjustable weir baffle, easy-fit filter sock holder(s), and four dosing line guides come standard. Additionally outfitted with High-flow™ and Tank-Saver™ technology, its simple to see why MRC© is the industry standard in aquarium filtration. Building success starts with MRC®.

Dosing Line Dock

The Sweet Spot
Adjustment baffles for water height is a custom feature on most sumps; the xSeries™ Sumps are custom units from the factory. Keep your skimmer doing its job while we do ours and you’ll be doing less work in no time.

Tank Saver Technology™
It’s not an optional add-on with the xSeries™ Sumps, it’s mandatory. Tank Saver Technology affords you an extra few inches of water height in the event something goes awry.

Pre Filter
We include genuine MRC® 200 Micron Filter Socks in every xSeries™ Sump. Our years over experience has shown us that getting the large particles out before hitting your other filtration components allows them to run more efficiently.
