All you need is a 75L de humidifier from lowes for 200 and change. A few diy mods and you'll have a chiller that will cool everthing you put chilling worts in. Its such a HUGE difference if you have a chilled rez all the time

Have you modified one? Got any instructions?

Just had a look at a couple (just two) and hmmm. Do you have a pic of how you got the evap coil into the res water stream? What did you use for the temp control?

You'll need a 25 ft stainless steel cooling wort for brewing beer. You can get one on amazon for around $40-$50. It will come with clear tubing.

Hook the clear tubing to the pump in the chiller rez and connect it to one hookup on the wort. hook the tubing from the other hookup on the wort and run it back to the chiller rez

The coil from the de humidifier just sits in a small cooler or some small container. Just lean it back and put it in there. Fill it up with water (the container with the de humidifier coil) and turn it on. Thats it. It will turn the water to solid ice if you let it. Just run the pump 24/7 and it will pump the cold water through the worts and its basically like having ice sitting in your water all the time.

For temp control get a regular timer and adjust it for cheap or a single stage controller and set it at 65 degrees or whatever you want and maintain the temp for around $120

You can run one pump to 3 worts with a T on the clear tubing. You can run more than one pump too so you can cool several rez's or put 2 worts in your rez or just 1 it works good either way.

That would be great. I've got a passive glycol loop and two tube in tube heat exchangers but only effective when below 40 outside, mechanical backup is gonna be a must me thinks. I've got the guts out of a water cooler but it may lack capacity, I'm only cooling 50 gallons at the moment though.

They have a 1/10th hp hydro farm active Aqua chiller online at Walmart clearance for $282. By the the time you buy a humidifier and by the temp controller for $120 twobrasin recommends plus parts you might as well get the real deal. Just my 2 cents

If thats the real deal it sucks for chiller users. It says it can cool 40 gallons 15 degrees in 20 hours.

I could cool 6 seperate 40 gallon rez's 12 degrees in 2 hours and 20 minutes. And only run a water pump for the next 12-24 hours and not get above 68 degrees.

This setup is more on the scale of the chillers that will run you in the $1200.00 + range.

Thats basically it. Its the piece from the de humidifier in the bucket and the pump feeding the worts. The cooler is for when the ambient temps get high the buckets sweats. Its not alot of water but i let fall in the cooler then it evaporates and to help with keeping it cool.

Oh then my bad. With your setup at that price then you can't beat it. That's what I need. Something that can cool up to 2-3 res's.

It works great because with this you're cooling the bucket of water and then the pump and wort cool the rez. With a regular chiller it has to cool the rez.

Dont get me wrong nothing against chillers but i found this in an rdwc journal awhile ago and it works great and saved money so was all good for me.

My plants are in their second week of flower, and I go to check PH & PPM and I have a lot of white snot / slime floating in my rez. It appeared over night.

Last week [4-5 days ago] I noticed some on my pump filter. I threw it away and put a new filter on. I figured it may of had some organic stuff in it reacting to the h2o2 since it was used even though I soaked everything in h2o2 before using. I didn't think much of it after that until today. I assumed that the h2o2 would take care of it.

I'm running a sterile system with h2o2 added every 3 days and Canna Flora a & b nutes at 1400 ppm with city water at 500 ppm to start. Just a little under maximum to prevent nute burn.
Air temp is always just under or at 80f. This should be good since I have a constantly running 6" intake and exhaust, and the LA air is full of co2 [smog enrichment haha].
I keep my PH between 5.5 and 6.2. That had jumped up over night as well to 6.7 with the addition of the floating snot.
Rez is covered. No light getting in.
I run two foam filters. One on pump in rez, and another on tray to keep hydroton from getting in the supply line. This is flood & drain. The water when in the tray looks fine. No snot in tray. It must be staying in rez since it's only floating on top.

I'm going to try dumping and cleaning the rez, then doubling the amount of h2o2 for first application.
My google search only came up with organic solutions to the problem, and one guy who solved it with h2o2. Since I'm running a sterile system, any organic fix is out of the question. Just wishing it would go away is not an option, although, my google search came up with that as a solution on a couple occasions.

I'm thinking about dumping the system every three days for a while while using a slightly stronger h2o2 mix and a weaker nute ppm. Canna's too expensive to just dump it every three days at full strength, but I don't want the plants to go into shock either. They are all growing vigorously, strong, and healthy with good color, and leaf profile. They appear to be very happy plants!

Anybody running a sterile system have this problem before, and if so, how did you fix it?

so you've noticed your plant growing more vigorously since you cleared up the slime? i had the exact same problem and just cleaned/sterilized everything in my tent and been giving the res a bunch of 35%h2o2 too. did you ever find out exactly what it was in the res? I'm thinking about getting a uv water sterilizer

Are not having algae issues with the clear tubing? I had to cover mine with black foam. Also it's pretty easy to size the needed chiller BTU requirements as 1 btu will lower 1 lb of water one degree. Sizing is important, too big and it will cycle way to much, more power and harder on equipment if buying one I mean lol.

You'd be better off controlling Res temps than anything else IMO. You could try a UV light and I would be interested in seeing if it works. My water system has a UV light but I don't circulate the Res water through one so it only hits it on fill ups.

The tubing or the chiller rez water never touch your actual rez water. Its a closed circuit. Ill get a pic the the worts in the rez for you.

so you just have a fluourescent light at the edge of your res thats putting the UV on the water? because thats what i wanted to do instead of circulate the water through a UV light. whats it not effective?

I understand u have a closed loop just wondering if it gets green? Probably the temps stop that from happening I would guess. My setup is a bit different in that I use seperate heat exchangers for each Res and run a glycol loop outdoors in the winter. Gonna have to come up with a closed loop for the res's though. Probably just build a chiller dedicated to the system or buy a used one. I'm a refrigeration mechanic so should have done the chiller thing a while back lol. I can't believe the difference a chilled Res makes for plant health, and growth.

No I have a whole house UV light. The UVC bulb that sterilizes water has an effective range of about 1-1.5" inches, the water has to flow past it. Also if you look at it you'll go blind lol. They make aquarium UV lights that pump water past FYI

oh i thought you meant the UVC bulb. but damn only 1.5"??? would my 2 airstones be sufficient enough for the pushing of water? lol id hate to put something else in my res thats going to heat it up. I'm at 68.4 so i don't really have room for much heat, although, i guess i wouldn't have to worry about shit growing in my water if i have the uvc bulb and h2o2 in my res lol
