I have looked far and wide for a DIY Temperature Controller for my chillers and heaters. I am looking for a DIY because I need to two for both of my chillers and heathers which puts the cost at 350 minimum for commercial controllers like Medusa and Ronco. If anyone has seen one I would sure appreciate posting the link :?
I found one that only costs something like $30, but it only controls one thing, either heater or chiller. You could use 4 of them, but that is still a little pricey, let me see if I can find the link... Sorry $65.... http://www.automatedaquariums.com/lv_ts13010.htm Hope this helps. I will bring the info to the meeting.
