Quick Overview

When power is lost to a system with a sump the water level in the sump will almost always rise up a few inches.  When power returns to the system the rise in water level can effect your skimmer and cause it to overflow due to excessive water level right on start up.  The solution to that problem is having your skimmer wait a few minutes before starting up.  The Reef Octopus Delay Timer will automatically keep your skimmer from starting for 5 minutes to allow your systems water level to go back to normal, before starting the skimmer pump. 

With External Skimmers the delay timer is almost a necessity, as it can keep your skimmer pump from running dry if no water is being fed into the skimmer. 

When the Red LED is on, Power is shut off to the skimmer
When the Green LED is on, Power provided to the skimmer

Product Questions

Can this be used to turn off the power to the skimmer while dosing?
Question by: ryan on Feb 1, 2016 12:56:00 PM
Great question!
This will essentially be plugged into the outlet, and the skimmer plugged into this unit. Any time the power to the outlet is turned off IE power outage or if with a controller the outlet is programmed off then this will (when the power is turned back on) hold the skimmer off for 5 minutes and then turn it on. It can be used during feed mode. Feel free to let us know if you have any further questions!

  • Problem solved! By Greg on 10/5/2016

    Always had an issue when turning my pumps back on after maintenance, feeding, etc with my skimmer overflowing until the sump water level decreased. Now, no problem! A little pricey, but the best stuff in this hobby always is. Very happy with my purchase.
  • Great for Tunze 3155 ATO By Bull on 8/16/2016

    This is a Great Delay timer for your auto top off pump assuming your using the tunze 3155.

    usually when the power goes off for a brief few seconds....then comes back on, the Controller on the tunze 3155 ATO has a pump primer issue, it automatically causes your pump to kick on and run for usually 15 seconds...which pumps more water in your tank then you need. Normally this isnt a problem but every 3-4 power tends to kick on and off several times in a 30 min time frame.....and within that amount of ATO was pumping so much water into my tank that my salt levels were dropping from the normal roughly 1.024sg...which caused alot of issue's....and the above delay timer solved those issue's.

    so what i did was bought the Osmolator Switched Socket Outlet for the tunze 3155 ato, this way i could plug in a normal AC powered pump for the ATO, so i have the Osmolator socket plugged into the above Delay timer which solved the tunze 3155 pump primer issue.

    now i no longer get the extra ATO water in my tank when i power kicks off and on being the PUMP for the ato is now on the 5 min delay....which makes this a must have if you have the same problem i was having.
  • I like it. By RandyB999 on 4/25/2016

    Works as advertised, once power goes out it delays start up of my protein skimmer for 5 minutes after power is restored. This gives the sump time to return to normal water levels before skimmer comes on, helping to prevent skimmer overflow (and all the skimmate being flushed into the sump)
  • Great By SaltyClaw on 10/12/2015

    I love this no more forgetting to plug it back in.
