DIY DIY Water Chiller

Does that pump serve as your primary one for aerating the tank or would it be a second one, hooked to a thermostat so it only runs when needed?

Using cold air would certainly be cheaper and easier to set up. What diameter will the line be connecting the pump to the fridge?

I use CFL but the room gets hot in the Summer they do put out heat. If I get a fridge I think I will put it in another room cause I don't need the heat from the fridge cooling coils making the room hotter than it already is. My air pump has an intake inlet. I never intended to circulate water through the fridge. I just want to suck air out of it for the inlet of the air pump. Cool nights work well but if I am going to grow in the summer when the evenings are warm I will need some cooling air. I agree with your assessment of ideal tank temperature 65 to a max of 70 degrees F would be ideal.

Hi Muddy I only have the one air pump. It is 1/2 inch pipe the kind that takes either crimp on connectors or those white plastic connectors you can attach with hose clamps. I put a two way valve so I can turn off the outside so when the temperature drops in the Winter I can shut the outside air off. I will probably put a second valve on to switch from the grow room air to the refrigerator air. I imagine I will stick with the same type of 1/2" pipe. The pump seems to suck air through it fine. The pump is a 900 gph one.

You don,t grow bubbly do you?

I'm going to be setting up an aero system this winter. Going to start with a 4 tray AeroJet and probably add more trays to it later. 20 gallon res and probably a second one if I add more trays. After the choppers this year I've decided no more outdoor grows so setting up another spot with hydro.

If a 1/2" pipe is sufficient then that might work for my application. I would probably run two air pumps then, one for constant aeration and the second on, on a thermostat, to bring in the cold air.

Hey Muddy. I never read the hellicopter incident on any of your posts. Must be scary to send you indoors.

There is one thing I didn't add besides tank cooling that I had to add after and that is a tank water circulation. I added a small water pump and now I circulate from the tank to the reservoir and back to the tank. I think it keeps the nuits better dispersed.

Your idea of two air pumps sounds great. I may copy it myself. The thermostat on one pump to only work as tank temperature gets too high is a great one also. Is the thermostat only hooked to the tank? I wonder if a second one could be hooked to the outside air temperature. No use circulating warm outside air through your tank. That might be counterproductive. I run my air through garden soaker hoses attached to the bottom of the tank with plumbing clips. Way better than those stupid rocks and way better bubble dispertion. My tank has four 50 ft. garden hoses clipped to the bottom of the tank. I was thinking of adding a thermostat to the outside air as well on my set up. Do you know of an electric switchable valve or maybe I will do as you do and just add a second pump and hook the outlets of the pumps together. I wonder of back flow will be a problem if the outlets of two pumps are hooked together and one is in the off mode?

I have never done a long run with the 1/2 inch hose. My short run with it didn't seem to lower the ammount of bubbles I am getting out of the soaker hoses. That is as scientific as I got on that.

here to helpDo It Yourself waterget a 60 pint dehumidifier or bigger take the entire case of you will see to heat exchangers insidethe one in front slowly bend down into a reservoir go to Amazon or wherever and get a temperature controller with sensor assemble the temperature controller to have full control ofthe dehumidifierset to a regular plug get an igloo ice chest I use a 120qt I have my dehumidifier stacked on top of the igloo with the lid closed my a good happen to have a little bit or on the lid so I could get the front heat exchanger bent down into it I filled up my igloo fulland watched the temperature go from 35 degrees Celsius 213 degrees Celsius in like 20 to 30 minutes while running an 8 inch hydro innovations icebox as my air conditioner because I'm running leds and and my tent is inthe garage and it gets hot where I live my tense does not get any hotter than 75 and with lights off it is 68 I am alos chilling 3 10 gallon reservoirs 2 63 degrees I will post pictures tomorrow let me know if this helps to anybody or am i repeating a different post I did not see it here so I thought I would help my water chiller cost me a total of $100and it works better than my old one quarter horse power personally I think it's pretty equal to a one horse power but I use a 6 pint dehumidifier

Water chillers made from dehumidifiers are simple to make ..open case ..put cold side in rez done! cools around 200 gallons very well..saw vids on the tube will be doing this very very soon!go on the tube look up DIY chillers.
