Product Questions

How tall is the skimmer cup section once it is removed from the body?
Question by: jonathan on Jul 30, 2015 12:38:00 AM
Great question! The skimmer collection cup is 7 5/8" tall. When the full skimmer is mounted you would need 25" clearance from top to bottom in order to comfortably remove the collection cup. Feel free to let us know if you have any further questions!

  • Great Skimmer - Super powerful, beautiful fit/finish By Kyle on 12/30/2015

    This thing is SUPER powerful - following the instructions and trying to get it to break in was interesting as it was producing SOOO many bubbles - I had to ease back on the air intake and lower the RPMs of the pump to one click above the minimum to avoid overflowing into the cup like crazy! I grant this is when the water is super cloudy etc. This pump is ridiculously quiet. I have a Reeflo external pump that is not particularly quiet, but it's on silicone and the silent pads; I didn't even know the skimmer was turned on except that the bubbles were being made. Very nice collection cup size for the size of the skimmer, fit and finish are fantastic; beveled and rounded edges over most places where you might touch it, great attention to detail. DC controllability is great. IF I had a wishlist - I would love Skimz/Neptune to produce some kind of integration with Apex/Neptune controllers as it has a DC Pump, why couldn't it use the variable controls for feed sessions/etc. I think it'd be a super powerful addition. Just my 2 Cents - really excited to watch this thing do work! :)
  • Excellent skimmer By Dave on 6/3/2015

    Excellent foot print for space saving requirements. I will agree the unit is very very quiet and the pump does seem to be oversized for this unit. Build quality is above average and I like the design. I would recommend this skimmer.
  • This MONSTER rocks!! By jon on 4/27/2015

    upgraded from a 150SSS and this thing is night a day difference, finally got it dialed in after a few days now i just empty the cup once a week. the pump is way over powered so its nice to dial it back. adjustment is easy and i like the gate valve over the pipe version for adjustment.
  • High performance for less money. By Aaron on 4/18/2015

    Great Skimmer! I own an aquarium maintenance company and service many tanks with every different type of skimmer. you can think of. This one ranks right up there with the best for its ability to produce skimate. The fact that this skimmer takes up less space in the sump is a huge plus. It's has low power consumption and the pump speed is controllable. Because of the more economical price point compared to other high performance skimmers, the Skimz Oval series is my new "go to". I love it!
  • So far so good By Micah on 3/15/2015

    After initially plugging it in, I can tell by the froth it will preform well with a low footprint!
  • This thing ROCKS! By Tom on 3/12/2015

    Just got this skimmer yesterday to replace a loud Bubble Magus Curve9 for a 150G tank. It's mainly SPS, and I feed very heavy. I hooked this up, and the first thing I thought was... is it even running? It's insanely quiet even when you put your ears up to it.. Second, it's been running for about 24 hours now, and already have a nice thick nasty 4-5" chunk of foam about to hop over into the cup. It's rocking and rolling and it just got turned on! This thing is awesome.. very highly recommend this skimmer to anyone.
  • So far good performance By Francisco on 9/3/2014

    Got this Skimmer for my 220 Mixed reef with very high bioload. I was experiencing a bid too much algae growth on the glass and was not happy with the skimmer I had. Within a day of setting up this skimmer my glass had very little algae and I now clean the glass about every 5 days. probably will get even better with time. I was specially very happy with the shape of the skimmer because it allowed me to fit larger capacity skimmer in a very limited space. I will give it 4.5 because it had no instructions, although not complicated to figure out.
  • Great Product By Don on 8/18/2014

    Contacted BRS when this line was introduced and am I glad I did. Great skimmer that has been producing high quality skimmate since day one on my 150G reef. It is in a 12 x 30 x 15 sump and the oval design allows it to fit nicely with room to spare in the skimmer chamber of the sump (about 16x12). I have had several commercial skimmers over time all the way back to the SeaClown (which actually worked OK on a 75 for me) up to this. Had the RedSea C-Skim 1800 which had pump problems and adjustment problems (giving me blood pressure problems) the entire 3 years I owned it. This skimmer has been none of that. Truly set-it and forget-it other than giving the cup and neck a thorough cleaning when it needs it.

    If possible I would give this product a 4.5 with a 5 almost never in my online evaluation review. Can't thank Skimz and BRS enough for this product.
