Tried reading the link on the 555 timer -

Definitely way beyond me. If you end up attempting something like that please keep us apprised of the steps you take and what not..

I found the right timer

A Chauvet light timer.

http://www.chauvetlighting.com/fixtu...imer_fix.shtml

You can set it from 1 second to 60 seconds, or 1 minute to 15 minutes. It can alternate between the two pumps. Goes for 'bout $30 on ebay. It's used for theatrical lighting applications. I'm going to call around the city tomorrow looking for one. Can't see it being more than $50 canadian. none of the e-bayers ship to canada, it seems

I'm going to play with a 555 timer simultaneously. I work at the source, and I'll just pick up a 555 from my store and play with it for learning's sake.

Dumb question maybe - what about something like this? Says it's adjustable from 20 seconds to 3 minutes and has alternating outputs..

Would you need the extra powerheads though? Surely there are some lying around town someone would sell ya for cheap if you needed some more.

I found the info about it being adjustable from 20sec to 3min on a different page, I just linked to the J&L page for simplicity. If you go to aquariumsystems.com and click Saltwater and then Accessories there's a blurb where it's mentioned in passing about the adjustability. (I'd just link the URL but the webpage is this primitive frame based thing and the URL doesn't show up properly).

The whole set up is pretty damn cool! I'm tagging along!

I bought one of these used. Maybe it was a quasi-lemon, but it wouldn't run anything other than a brand new maxijet. Older ones or other brands of powerhead it just didn't seem to have enough juice to turn on (on the switched outlets).

I've used these timer/wavemakers twice and they were awesome. I used them with hagen powerheads, 801s plus Pro4s and Rio 2500's I never had a powerhead not work with them. I would have used one again but I've read Seios don't do well with on/off cycles IE a timer and I really don't want to spend $200 on a Seio controller. For now things seem to be working with two 620's on 24/7 and an 820 that comes on when the Halide comes on.
