Berlin System/Sump | Nano System/Sump | Prefilter/Overflow | Protein Skimmer | Refugium/LifeReefugium | Wet/Dry Trickle Filter



Below are just a sampling of the hundreds of custom projects that have been designed and fabricated by master-craftsman Jeff, at Lifereef. Perhaps one of these designs will work for your application. If not, let Jeff's 31 years of design and machine tool experience help you with your project. Those "generic" three-chambered sock/bag things are nice starters but lack a lot of what makes a sump or sump/refugium a joy to use, or a "pain to maintain".

Lifereef sumps and sump/refugiums and systems offer VERSATILITY! You don't know what you're missing until you use one of those other sumps and find out what it should have had.

In fact, the majority of builds Jeff does are for hobbyists wanting to get rid of their current "system" after finding out the problems and lack of versatility, and sore knees! They've put up with it long enough and it is now time to replaced it with a Lifereef system or sump!

Dimensions can be changed on many of these designs (hence "custom") to fit your cabinet space and Jeff will discuss this with you to make sure of a nice fit to maximize the space. Jeff will then use his years of experience to design a sump to offer versatility for example: Connection ports for R/O top-off line and a Calcium Reactor, drop-in Filter Cylinders or drop-in media reactors, probe holder, LifeReefugium, etc. Your sump or sump/refugium will look like a fine piece of machinery, not a conglomeration of stuff stuck together with pipes, hoses, and some good luck! Not with a Lifereef. Even the simplest of sumps will have a better look and finish than those generic acrylic boxes.

And MOST IMPORTANT, if you have a protein skimmer Jeff will make sure that your sump or sump/refugium is designed to work with that specific protein skimmer. Your sump and protein skimmer must work together and that is the biggest problem hobbyists face, and usually don't find out until it is up and running, and then here come the fixes, mods, try this, try that, etc.

Remember, custom means Jeff can build sumps and sump/refugiums for any application and most any size. And not only sumps: How about a reservoir for top-off water to fit that small space behind your cabinet or inside your cabinet? Or how about a multi-tank reservoir to hold several liquids? Need DIY stuff, Jeff can supply you with tubing. sheet stock, and with the CNC Computer Controlled Router Jeff can fabricate your parts with precision accuracy as he does with many of the Lifereef products and components.


Custom Reef Aquarium with filtration/skimmer in back:

Customer request for an integrated Lifereef Protein Skimmer to be used within an aquarium/sump system. 24 x 24 x 20 footprint which included a custom made mount for the Radion RX30w Pro. Go here masinireef.blogspot.com to read and see more of this fantastic nano tank.....


Hobbyists desire to get a large sump into his stand required a four-piece sump array "bolted" together with the interconnecting bulkheads. This design was the customers, with a review of the design to look for any potential problem areas. Overall size is 44 x 21 x 22 high. Water enters into the right sump (a Lifereef VS3-36 skimmer is connected externally to this chamber) then flows into rear center sump to the left, then reverses flow to the right where it enters the front center sump and flows to the left and enters the left sump where a submersbile pump returns the water to the aquarium.


Hobbyists cabinet has center storage area so sump had to be split into two sumps connected via two 1" lines run behind the center area. Left sump has input chamber, mechanical/chemical chamber, and skimmer chamber. Right sump contains the return system pump and the Lifereef Accessory Rack to hold media reactors and a bio-reactor, and probes. As soon as the user gets this installed and provides a photo I'll be posting it here.


And many many more customs!
