Our dLUX Sump Kit for 20 Gallon Long Aquarium is designed to convert a standard 20L glass aquarium into a full featured luxury sump.

The sump/refugium is a great all-in-one filtration and nutrient export system for reef aquariums up to 55 gallon.

Just grab yourself a 20L glass aquarium available at Petco for $40, occasionally on sale for only $20. Then all you need to do is silicone the sump kit in place with aquarium safe silicone to complete the setup.

We recommend GE Silicone for Plastic that will bond well to both acrylic and glass vs regular glass silicone, and it is completely reef safe. Please pay attention to the “expiration date” near the bottom of the tube when purchasing, an expired tube can be frustrated to work with and won’t fully cure.
