If you are blowing a fan across the top of a tank, are you likely to see more evaporation? Does that pose a problem in saltwater tanks?

No, the salt doesn't evaporate, the water does, so we just top off with FW. There could be a problem if there is too much evaporation and no top-off, the salinity would continue to rise.

Right. I was considering if one were to go on vacation with a fan cooling the surface of the water. Eventually your salt concentration would be higher, but I suppose it is very gradual.

Mini fridge - $200
100ft tubing - $100
Pump $50

Guys over at RC have had decent results...but they are only running around 50gph...

I would try out the fans first as mentioned. And if that doesnt seem to work, your best bet would be a real chiller.

To me thermoelectric heaters look pretty simple. I thought someone somewhere had plans on how to make one. I have a minor background in electronics that is why i am asking.

Yes, this is also a problem. Hopefu;;y they would have someone to feed their fish and then just add top-off water, or you could get an auto-top off unit.

I think Marc hit it....the mini fridge is what I thought of with a lot and I mean a lot of tubing coiled inside. Like he said you are talking about moving the water through it very slowly to allow it to chill, even then you have to manage it so as not to over cool the water causing you heaters to go nuts. I don't know...sounds to me like a store baught chiller is in order.

stainless steel plate heat exchangers would be what a store bought unit would have in it..

one could use a small window air conditioner (~ equal to a 1/2HP unit) and have the condenser replaced with a stainless steel brazed-plate heat exchanger (3-4 plate would be plenty) then the capilary tube and the reifergerant charge would need to be adjusted for the heat load the system would put on the phase change system (the converted air con.).
Then heat load changes with the lighting cycles so it would need have an on off cycle.

level 6 out of 5 DIY (the project involves breaking into a phase change loop, wich unless done corectly is illegal) unless you happen to do refigeration for a living (or have a freind that does) then I would give it a 4 out of 5.

I never even thought about that. Plate and frames allow you really efficient heat exchange with close passes, but you'll be worrying more about seals breaking than with a traditional tube heat exchangers, because each plate is going to have its own seals. When it comes down to it, home made chillers probably aren't worth it.
