So far the fan and 1ltr bottle have done the trick; lowered the res from 25*C to a steady 22*C.

Has anyone tried making nutrient ice cubes? Could one make a nutrient mixture and just pour it in an ice cube tray (or five) for later use?

Ive been thinking of using a water cooler, Just turn it down a bit and run the water in were the 5 gal. bottle was and put a fitting on were the nozzle is and have the solution running through the cooler into the res. I can find these all over, as many people get rid of them for newer one's, and I don't care if they look old or nasty. What do you guy's think?

pk, that is a very novel idea.
They only drawback that comes to mind, is that they are not really designed to cool continuously moving fluid.
I think until I was sure what kind of load it could take, I would put it on a timer of some sort.
I think your idea may be a very good one for top-feeders, coco-nuts, as well as ebb and flow guys.
Post up pics if you pursue it please.

Sorry to go off on a tangent, but this discussion reminded me of a similar idea I had for temp control in a small grow space. Was wondering if it would be possible to get one of the water coolers that also has the hot water tap, put in solenoid valves on the hot and cold, and have both feed into a small heat exchanger (thinking a radiator of some sort). Put that on the intake vent for the space and have a thermostat to turn on the hot or cold depending on if you wanted the air coming in cooled or heated. Out from the exchanger would loop back into the jug on top for re-use. Don't quite remember what I was smokin' when I came up with the idea. :smoking:

Think about it GB. You use a cooler for your rez. with insulated plumbing you would not loose much temp when the temp finale levels out. The only thing keeping water from running all the time is the outlet. Im thinking 1 on power saving mode would work great. I plan on testing this out but it will have to wait till I get ready for the next grow
Why not use... an aquarium water chiller? 
DIY chillers that wok properly is really really hard. But not impossible. Just dont think a little fridge will do the trick. There is a reason proper aquarium chillers don't do miracles and need to be bought with great care. Proper wattage and matching water flow/pump...
Just saying, don't be spending too much on a project and end up wasting cash. If you can get stuff dirt cheap, then why the heck no try though
And yeah, insulation goes a loooooooooong way in helping. Think about creating a gap between the bucket and the air outside. Do a double layer of bubble-warp on (inner layer), and reflective on the outside. That does indeed do miracles. Cover the sides, pipes, the top lid, everything. Be paranoid about it and it will pay off.

Coolers are free a lot of times, say $12.00 in fitting hose and claps. I already have all of this stuff, so no out of pocket. It would take mabe 25 minutes to set up. You have to know that coolers that are used 24-7 need less to keep them cold, My cooler that I practicaly live out of only takes about 2-3 pounds of ice a day. If I don't put ice in it on one day, I can put a whole bag in the next day and it will all have melted by 4:00pm. once you get it leveled off it wont take much.
This is what I'm gonna try with the spare lid I have. The blue circle is going to be a plastic vessel that I can dump ice into; if I make the icecubes out of RO water with a balance ph, I can just dump the melted h20 in the reservoir and top off the ice container as needed. The two black squares on either side represent two cut outs for 80mm fans to be mounted in.
