I use propylene glycol/ RO water 50-50 it keeps the lines inside of the chiller lubricated and resists corrosion.

I hear ya. I was actually thinking the copper was better because it was more expensive.
Do you use that a/c for your chiller?

No copper should not be used in the buckets with your nutes look it up this guys is the only person I have ever heard say copper is fine because it is not.

I was going to go with the stainless steel. Most everyone has said the same about copper so I made my decision based on the overwhelming majority.
No offense, fab

Trust me I wish copper would work cause as a plumber I have tons of it, but unfortunately it will wreak havoc in your system after I few runs and a 50 ft coil of stainless steel is only about $70

I have yet to see anyone make a blog, post, website claiming "copper coils are terrible they killed my crop"
if everyone is under the assumption that copper is bad and everyone uses stainless there is nothing to compare to. I guess I'll be the lone soldier on this one lol. Been running it for years with no problems. Maybe it's the nutrients i use who knows.

Again not trying to get into an argument with you but I was simply pointing out which JSB also points out there is a reason that everyone says to not use copper and since I have seen how certain things corrode copper big time. Also this is the standard when setting up anything not just hydro grows. When setting up hospitals and food centers with all the plumbing necessary anything that is going to be used for human consumption or anything that needs to be sterilized , stainless steel is the only thing used never copper because of its corrosiveness

I'm not trying to say use copper. I was just letting you know it works for me. Everyone has there opinions on what works an what doesn't work. Fortunetly copper works for me. I can't use the stainless coils in my systems because the diameter of the stainless coil is much larger, i can make copper coils half the size. I think 3/8" stainless can only be made into something like a 10"-12" diameter coil before it starts kinking.

I agree with this that copper is more corrosive. I look at my coils though and see no corrosion. Maybe this is because they are 99% of the time submerged in water and have very little contact with air. I see what you're saying but since you're a plumber i know you have seen 50 year old pipes in a basement all green, corroded leaking from the joints and when you replace them the inside of the pipe has went from shiny to dull, no green and corroded like the outside. You don't see the same corrosion on the inside of the pipe as you do the outside.

In the end, that's all that matters
