How to clean nutrient buildup in water chiller?

What would anyone suggest for flushing my water chiller? Its on my single bucket dwc. I plan on changing it over to run plain water after this harvest, but for now, its recirculating my feed water. I see some buildup in the lines. Today is water change. At the moment i am flushing with bushdoctor. I usually flush fir an hour and it removes a lot of it but thinking maybe doing 2 hours and see if it helps clean better? Any advice?



Vinegar is excelled for removing salt deposits (in an empty container btw grows,) but be sure that you rinse well when done, as vinegar is an acid.

Not exactly what i wanted but its what was available. It’ll work for now, keeping chiller water separate from my feed water. Ill run some vinegar through the chiller at the end of this run. Thanks for

Let’s get @Myfriendis410 to weigh in. He’s a great hydro guy. I haven’t seen Sledgehammer used in hydro grows much at all. Myfriendis410 will have good advice for something you can do mid-grow. Vinegar at this point would burn your plant’s roots.

You will need to disconnect from the rez and bucket and create a closed loop by input and output tubes poked into a bucket. Use a strong peroxide solution like one to one of 3% and water then let the pump run it through the lines for a half hour. Peroxide will dissipate quickly and a quick rinse with water should set you right back up.


I built this today. Now clean chilled water outside the bucket and nutrient solution inside. Ill give it a good cleaning when this plant finishes. Thanks for the info

Tubing is so cheap, why not just replace it? I agree going forward to have the coolant water separated from the reservoir water in a closed loop. But for now, just replace the cloudy lines, clean them, and keep as a backup perhaps? That tubing is like 50 cents a foot at my local ACE Hardware, Home Despot, or Lower than Lowes. Great looking plant.

Just figured the chiller tank looks like that too, so when i try to clean it, i can see how well its doing through the tubing?
