Product Questions

Hello, what is the water level requirement for this simmer?
Question by: Kent on Aug 21, 2014 3:43:00 PM
Hi Kent,

I was unable to find a manufacturer recommended depth for this skimmer but I would say, based on similar skimmers we have running here, that aiming for around 6 - 7 inches would be a great starting point. Waiting for the skimmer to fully "Break in" before adjusting too much is important as you may have trouble getting stable performance from the skimmer during the break in period.

I'm sorry I couldn't give you a definite answer.
Have a great day :)

  • Great Skimmer By Jeremy on 1/16/2016

    Upgraded my tank and upgraded my skimmer. I couldn't believe how much an improvement this skimmer was. It was a snap to tune, broke in quickly and I love the controllable DC pump. I hope Skimz makes a auto neck cleaner, because then this would be perfect.
  • awsome skimmer By chad on 2/23/2015

    great skimmer nice foot print and skims like a pro this was a good upgrade from my sro 2000 way better skimmer
  • Great Skimmer By SonoranReef on 12/29/2014

    I purchased this Skimmer from Bulk Reef Supply. While it is a bit overkill for the 140 gallon tank I an setting up I could not beat the price when they put it on sale before Christmas.

    When I set up my 140 I used VERY cured live rock from another tank, new reef sand and salt water made with RO......So the water should have been Very clean , well the next morning I already had Skim.

    Love the adjustable pump, sure makes it nice to not have to prop up the skimmer to get it at the right height.

    My only complaint is the instructions were not the best and they took a little translating. Overall very happy !
  • Amazing Skimming Machine By rick on 10/26/2014

    This skimmer fit perfectly in to my Aqueon sump and went right to work. It skimmed off more gunk in 24 hours than my previous skimmer did in months. The adjustable speed was great for the short break in period and the feed mode is a nice feature for when I shut the recirc pump down to feed my dendros and sun corals.
    I love it!
