Hey Trev, guilty as charged. Could I suggest that you use a separate
power bar for your heater & filters. You could even include the lights
if it would help you remember to turn it back on.

I built my own delay-off timer, and I'd be glad to share the directions
and schematic, but it's not your average DIY job. I used 3 electrical
junction boxes, #1 had a GFI outlet for the equipment, #2 had a standard
delay-on timer and #3 had a 120Vac DPDT relay which I wired into the
delay-on timer.

I also built a similar device. I call it the feed'o'matic :-) I press the
feed button and the attached devices turn off for around 10 mins
(configurable).

My device is based around a 555 timer IC and a relay. Definitely not DIY
material unless you have an electoronics background.

I can provide a schematic and Veroboard layout if you're really interested.
