[APD] Re: Timers
X10 can be temperamental. Line noise can be a problem, especially with
older wiring. I use it for some household lighting, but not my
aquarium. Computer integration is a big plus though.
Another option would be to use 12vdc activated outlets. I have seen
power strips that are being made for aquariums on the internet. I can't
remember an address right now, however. These are then controlled with
an inexpensive lawn irrigation timer. The irrigation timer uses 12vdc
as a control signal for the outlets (relays) and allows more complex
timing schedules than most outlet timers. You can probably find 12vdc
outlets through home automation companies.
There is also a digital timer at Aquatic Ecosystems that, I believe, can
have 6 on & 6 off events a day for a minimum interval of 1 minute. It
is a 7-day timer so each day is independent. $42.00
Hope that helped,
