  • Excellent product By deutschmick on 9/2/2015

    Well made and easy to dial in. Small footprint in my sump for a 120 gallon FOWLR (soon to be reef) tank. As many have said previously, buy a skimmer that's a higher capacity than you think you'll need. As I've previously discovered this is not an item to skimp on. Highly recommended!
  • Great BRS Support By Redtigrinus on 8/25/2015

    I recently had a part on the skimmer break and I called up BRS and they got me out a replacement part in less than a week! So they are in fact handling part inquiries. During that time I also figure out how to tune the skimmer, and honestly I felt stupid afterwards because it was that difficult. Since tuning it as been working even better than before! Great Skimmer.
  • Not bad at all! By Redtigrinus on 8/12/2015

    I get pretty good skimming from this skimmer but it does take some tweaking. Dry skims like a champ, but I haven't quite figured out wet skimming yet. Nonetheless it is doing the job. Though if I had it to do all over again I'd get the DC version.
  • Quality Skimmer By Crawford on 4/27/2015

    This is the third skimmer I've ever owned and it works better than the other two that I've had on previous tanks. it took a little while to break in and the only reason I gave it 4 stars instead of five was because it's a little confusing on how to tune it to your tank. Playing with the water inlet and the air inlet gives you a ton of control, but also means you have twice as many things to regulate.

    Skims well
    Quality Materials
    zero microbubbles come out of the return

    Adjusting skimmer can be kind of a hassle until you get it dialed in
  • 2 month review By Stuart on 2/1/2015

    Now that I have had some time to play with the unit and run a more wet or dry skim I think overall it is still an awesome product. Very easy to take apart and clean and once it is set I leave it go... Every week I drain the cup and always full of gunk! Def a quality product and worth every penny!
  • Awesome sauce.... By Stuart on 1/9/2015

    I have a 100 gallon system total. I have now been running this skimmer right in my refugium. Fit perfectly in the small space I had remaining. I tend to have to make adjustments quite often but I would say overall I am impressed with the job it's doing. Skim is a range of dark to lighter.... Depending on feedings and water change schedule. I have used many skimmers over my time in this hobby and almost obsessive career as it feels sometimes. Quality was also outstanding. I would def. recommend this product.
