Now I understand... at least in part. Using a thermoelectric pad as a chiller, interesting, I've used them in computers with watercooling rigs... Never thought about using it for a cooler for a tank... 228w of cooling power might really have a pretty good amount of effect in a smaller reef, what else is used for the heat exchanger?
Tagging along. I just picked up some 40mm peltiers for next to free, but I haven't figured out how to use them yet. I thought they'd be good on my 2.5G tank. I wonder if you can drill and tap titanium? Hmmm....
Okay so I have a few questions because I think I may have found a decent chiller for nano's. What is the lowest temp you want to go? Would 75F be a decent temp for the tank? I know I've read 72-80 and I know 80 is high. I know that 75 would be just under half that. I found something and don't want to reveal it yet becuase it's kinda strange. But if I could get those questions and any other info that you may want to provide for temp I'll reveal my source.
The 'ideal' temperature for your tank would be hard to determine, more specifically you'd be looking for what the average normal tempuratures are in the wild for the species you are keeping... but in a perfect world we would all be caring for captive raised animals, so the ideal temp would be whatever they have adapted to living in over generations.
With some exceptions 78-80F seems to be a well tollerrated temp for most specimins.
