Reddit mentions of EcoPlus Eco 185 Water Pump Fixed Flow Submersible Or Inline For Aquariums, Ponds, Fountains & Hydroponics - UL Listed, 158 GPH, Black

I've done something similar. I chained my buddy's chiller in front of mine and put his in a bucket with ice water once the wort reached about 130 F. Previous brew day it took an hour to chill my wort to 80 F and it just would not go any lower. With the pre-chiller it took 30 minutes to reach 70 F.

Another option is using small pump to recirculate ice water. I have this 185 GPH pump and it isn't quite enough for a good flow. Get something with a higher flow rate if you go this route.

Using some copper tubing from home depot coiled into the correct shape by coiling it around something. Added a few feet of braided vinyl tubing and hose clamps, and hook it up to this immersion pump. That goes in a big cooler with cold water and ice, plug in the pump and let it go to town, with the output going back into the cooler. Sometimes I'll do a run of just cold water for an initial temp drop, and then drain the cooler and replace with freshly cold water and ice to get it down to pitching temps. If I did it again, I would probably go with a more powerful pump, maybe the 396 gph model.

Here is a good visual/guide of what it more or less looks like. A good how to video on building the coil itself is [here}(https://www.youtube.com/watch?v=K8xRGYnwEt8), and the way I did it I save a lot of hassle and cost by just using tubing with clamps instead of plumbing connections. It's definitely good to make your in/out tubes to up, out, and then angle down like this so if it leaks it won't get in your wort.

What kind of pump do you use? I set up something similar to this with a small fountain pump, and it sucks. The water moves through the coil, but only at a trickle.

This is the pump I used: http://www.amazon.com/gp/product/B0018WVNXC/

Sorry for not including info.

It's actually a 158gph submersible pump: http://www.amazon.com/gp/aw/d/B0018WVNXC/ref=mp_s_a_1_1?qid=1427527694&sr=8-1&keywords=eco+158gph

I bought a 1/2" hose, and an adapter that allows you to screw on garden hose size attachments. I just mix everything in a 5gal bucket (for now). So far, it's been totally worth the investment! It was about 50-60$ for everything at my local hydro store.

I just set up a really basic watering system so that they got watered while on vacation, using:

I timed how long it took for the pump to go thru a 5 gallon bucket (my normal amount to water) 3 times, and set the timer to go off for a little longer than it took on average, on the day I wanted them to get watered.

I'm now using it to water since I'm in flower and it's easier to just let it water them while in darkness, since I'm only awake for a little time they are getting light.

Alright, so let me just put a little list together of what I need so you can confirm that it'd work. :P

Would that set up be able to sufficiently wet the belt to prevent heat build up? If not I may just bite the bullet and get an air compressor and a Kool Mist system. :P

Here's another idea which is a twist on what I do. I have one of these pumps. I put it in a sink full of water and ice and use that to feed my chiller. It works really well but you have to have lots of ice.

Just a heads up, you can get a submersible water pump on Amazon with free shipping (if you have prime) for $15 that does 158 GPH. It has several hose adapters, including 3/8. Not sure what your water pressure is like, but this is way faster than my sink at home. You can also chill the water and recirculate it. Just a thought.
