Timer Question
 

Is there such a thing as a timer that has two plugs, and it will switch from one plug to the other, so that when one is on, the other is off that you can set to do...say, 30 or 60 minute intervals?

Look into waver makers such as here

woods dual-outlet timer, thats the one i'm using myka, it's got some 20+ programs set on it to choose from. I've been using it for a couple months now, and once you get it figured out it's real reliable, and if theres ever a blackout it remains on and charged, so you don't gotta reprogram it :smile:

Both of those sound waaaaaay more expensive than what I'm looking for. I'm looking for just a simple $20-30 piece of equipment that I'd hopefully find at Home Depot or something. I just want it to run 2 powerheads so that when one is on the other is off. It's for my baby Bangaii's, and if both powerheads are on together it will be too much flow, but one of the powerheads is a return sort of thing. I don't want the return to run all the time because it will flush the BBS out, but I don't want their tank stagnant when the return isn't running either. So I want the powerhead to run when the return is off, and the powerhead off when the return is going. Hard to explain...lol.

I think this may be at least close to what you are looking for. I use it for lights. The blue and yellow outlets alternate... when one is on the other is off and vice versa.

Hey thanks! That's close, but "Can be set to turn on/off 7 times per day" means it won't change it up often enough. I'm thinking if I can't find the type of timer I'm looking for that I will just use an airstone for circulation while the return is off. That would be easy enough...should do the trick too. :)

no, the woods timer is only $15, has so many programs like timing intervals for instance. for me it's real straight forward, go on at 12 and go off at 7.

I wonder if the mechanical version would work better for you? I would guess that you can program it on / off as many times as you want in a day.

I would steer clear of the coralife timers, they do not have a very good reputation.

mik_101 got one a month ago or so, and he barely, just barely programed it, there a disaster in terms of programming the times and intervals you want, in general i'd never get a corlife timers myka
