Poor manufacturing

The hoses that came with the unit did not have proper adapters installed. You cannot glue an MPT-Slip adapter on a spiral hose! As a result both hoses were leaking and had to be replaced. The sump itself, BS-2, had a pretty poor gluing job. Lots of bubbles in the seems and too much glue. I am not a structural engineer but it looks like the acrylic (at least it's cast not extruded) is too thin for this kind of a sump. 18 months later, I can see significant outward bowing in the panels, several seems have bad crazing, and one panel developed a 4 inch crack. I never abused the sump, never dropped it, never subjected it to excessive heat or vibration. It's very disappointing since it wasn't exactly cheap.

Sump

I wish I had gotten the larger size sump for my 90 gal tank, the volume is roughly 18 gal. My Eheim 1260 is a tight fit with the base on, but no other problems getting other components into the tank so far. Over all I am happy with my Berlin Sump.

Berlin Sump

I bought a berlin sump to go along with a 4" sock for filteration. I had to buy this because I was unhappy with my old sump that I paid $225 for. Let me tell you.. I paired this sump with a ASM G-2 Skimmer, and within a few minutes I could notice changes in my water clarity. People are right about the sock though, it is a challenge to clean. If you want to properly clean it, it's best to put it into the washer w/only bleach to get it to turn white.. and to kill any kind of bacteria caught in the filter. The number of microbubbles is remarkably lower than the previous sump. I would recommend 1 thing... when it says "sump only" don't do what I did and buy the sock adapter.. it already has a place for the sock.. This item for the price is a really great addition to my reef. I did notice some cloudiness within the first 2-3 days of hooking it up.. so rinse the sock before you use it.. either way I don't think that is preventable.

I replaced my 30Gal glass homemade sump. This sump is huge improvement. Plenty of room for skimmer Aqua c 240 with 1800 gal Mag pump. This sump allows you to drill out for bulkheads and mount your skimmer pump on the outside of sump, keeps pump from overheating your tank.

Be prepared to change the filter 2-3 times a week otherwise it will get filleg with stuff and bescome a nitrigen pump with or without a Skimmer although its recommened that you use a skimmper , it make no dfference either way

excellent

amazing results after adding this product to my tank. Maintence is much easier than the homemade one I had. I did have a bit of trouble getting it to fit in my 120's stand. I had to remove a brace to get it to fit, but overall it is a great product. always go big with a sump :)

so done with HOB

i was done with my HOB skimmer and will never go back after plumbing my first sump. a little overkill for my tank, but you can't argue with the results. enough room for some extra rock and protein skimmer. definitely wish the smaller bs-1 had bulkhead the bs-2 has on the return side, otherwise it would have been 5-star.

Nice sump!

Its big enough to fit all my gadgets (skimmer, calcium reactor, heater and probes), and has nifty ports to connect hoses & the filter sock to. I drilled a bulkhead on the exit side, which works great (connected an Iwaki 30RLXT pump for the return). I'm running this under a 90 gal tank. So far, so good! I've got a shorter cabinet, and this unit fits under with room to reach the skimmer.
