Here's the companion part to the DIY Feeding Timer I made. This is the equivalent sort of thing to the Reef Octopus Skimmer Delay On box, but less expensive.
This allows me to automatically have my ATO and my protein skimmer turn off when I use the DIY Feeding Timer I made (see my post on how to make it) to turn the pumps/powerheads off to feed, but not turn back on until some preset time after the pumps/powerheads come back on.
Here's the parts list:
Delay On Timer (user can set from 0.03-10 minutes delay): https://www.supplyhouse.com/Packard...MIx820oPaagAMVyvLICh3kIwX8EAQYAyABEgL5HfD_BwE
2-gang weatherproof box: https://www.lowes.com/pd/TayMac-2-G...ard-Switch-Outlet-Wall-Electrical-Box/4005491
Waterproof cord conduit fitting: https://www.lowes.com/pd/Sigma-Electric-ProConnex-1-2-in-Cord-Grip-Connector-Conduit-Fitting/3150211
Outlet (can use GFCI if you want): https://www.lowes.com/pd/Eaton-White-15-Amp-Decorator-Outlet-Residential-Outlet/1001438384
Extension Cord: https://www.homedepot.com/p/Southwire-8-ft-16-3-Outdoor-Extension-Cord-in-White-277563/301132618
Wall Plate: https://www.homedepot.com/p/Leviton...e-1-Blank-Wall-Plate-1-Pack-80708-W/301701277
Optional is to use a female disconnect fitting to use when you connect the hot wire to the input/output spade connections on the relay. It's pretty tight in the box, there's not much room to use a spade connector, so I soldered the hot wires to the relay and bent the connections down some for plenty of clearance.

The Delay On Make Timer has a red knob that allows you to preset the power-on delay for your ATO/skimmer up to 10 minutes after your pumps come back on. I have a 30 gallon sump on a 125 gallon tank, so I set mine up for a 5 minute delay, although I probably could have set it for a minute or so and been just fine. Once the timer is set and in the box you'd have to take to cover off to reset it to a different time delay.
The extension cord is to supply power to the unit, I cut a foot or two off the outlet end so I'd have some spare wire to use. The cut end goes into the box and the relay and outlet wires up to it, the plug end plugs into the feeding timer outlet.
*** One thing with this unit is that it's only rated for 1.5 amps, which, at 120 volts, means it can power a maximum of 180 watts output. That's plenty, though, to run my Tunze Osmolator and my Curve 5 skimmer. ***
Attached is a .pdf file showing the schematics.
Also attached is a picture of the relay I used, showing the wire loop you have to clip in order to use it on a 120V circuit.
