Nanotuners DIY Chiller

[Kenny_Graham]

Does anyone know anything about "228w TEC - Swiftech" or how it works?

[mummra]

do you have a link to what you are talking about?

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?

I need to explore somemore.

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....

check this out its the same idea. im working on making one similar the main problem is i cant find just an arcrylic block at any stores.

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.

So would 75F be too low. The reason I ask is with the Aquapod it's pretty difficult to keep the tank below 80with the lights right on top of the water and no air circulation other than the small fan. I have an old humidifier fan on top of the tank drafting air through much faster and much more cfm. It's holding at about 80 if not just over 81.4 was the highest today.

[lamajo25]

Here's the reason I'm asking. This could be modified to have a bottle type item inside it with a recirc pump. The top cool temp is 75 with a top temp of 122. Obviously you wouldn't be able to go higher than the 75 and definately not lower. But I think it might work. Cheaper than a chiller but not as difficult to get ahold of parts for the diy chiller.

it should be ok, but i notice when i get over 82 my corals start to react to the temp. so i keep mine right at 79-80 and they seem to love it cuz they are growiing like weeds.
