Can I hijack this thread since OP question is answered? What if your going to be gone for two weeks? I have 5 tanks, and no one I know keeps fish. Three are planted and only two are on the same power supply, so timer will not work.
Surge protector + timer won't work?
OP: yup, leaving them off will be fine
THey are too far apart in the house, I wouldn't be able to get them all on one strip Or I would do that!
Ah, shucks. Multiple timers then? You can find them for 3-4 dollars often.
If I found one for $3 I would buy it in a heartbeat! Where do you find such deals?! They sell them for $20 cheapest here
