  • Great Product, Not So Great Packaging By Deandre on 10/1/2016

    So far, the only problem I have is with the packaging. The product runs great. I'm still tuning mine in, but still pulls a good amount of organics out of the water.. When I received the skimmer, the box showed no damage, but one of the pumps housing was cracked in multiple places. BRS fixed that problem quick and easy, Thanks! Now that I have it running the pump that came with it seems louder and doesn't seem to produce as fine bubble as the replacement. Good thing BRS carries parts! I can test my thoughts.
  • BEst skimmer for the price By andre on 7/21/2015

    I have a 150 gallon mix reef tank and during maintenance broke my old reef octopus that was rated for a 300gallon tank. went shopping around and after reading lots of good reviews on Skimz products decided to risk it and try them out. Breaking the my old skimmer turned out as a positive for me in this case because i will be upgrading my tank to a 724gallon in the near future 5-8months(structural work been done to floor for weight ). Now i know that this Skimz Monzter SM252 is Rated for a 793 gallon tank but on my 150 right now its working wonders! i have it set to skim nice and dry and its taking out 2-3 times as much durty junk out of my tank as the old reef octopus.
  • I love this skimmer! By Joshua on 6/29/2014

    I bought a sm 252 almost 3 years ago. It is still running strong. I get some of the nastiest dark skimmate from this skimmer. However I would recommend not gravity feeding it. Use a appropriate size feed pump.
    Very easy to clean, being that the bubble plate is removable.
    I beleive I will be purchasing the new dc oval for another system.

Can you recommend an ideal feed pump for this skimmer?
Question by: Ty Basinger on Mar 31, 2016 8:45:00 AM
Great question!
I have listed 2 pumps below which can work great! They are slightly over powered to help deal with any head height and plumbing reducing the flow. If not much distance is needed you can select the size down from each pump as long as it is above 750 GPH or so. Feel free to let us know if you have any further questions!
