Nice attitude Kirk. That had nothing to do with my comment. Pm me to discuss.

yeah or a phone call lol. I was kinda in shock myself. kinda a poor attitude.
Especially when he finds out what the real inference was meant for. I don't see how I have skin in the game either as I know nothing about the subject!

i have copper pipes in my house. I've done as large as 50% water changes and no problems. I've left the hose on all night and killed many of my fish from chlorine or chloramine idk for sure. but russ had 5 figure fish In his pond and all was well. winter only lasts so long. so back to the same old thing. does long term exposure matter more. hard to say really..
No need. I took your posting the wrong way. My apologies.
Reading the articles I posted and others. It seems that all ponds are different on how they can deal with levels of copper. So it comes down to the overall system. However copper stays in the koi's tissue. Like mercury in fish from the ocean I guess.
Apparently if a koi is exposed to low levels of copper for an extended time. It can create health issues.
It would probably be a good idea to periodically check copper levels in your pond if copper is introduced.

Copper like other minerals, in trace amounts, are needed in proper physiologic functioning. Anything higher than what is required can be considered added stress; something that the kidneys and liver have to deal with and spend extra energy regulating. Though you can heat water in a copper exchanger (and use ion-gen to get rid of algae), you risk adding copper far more than is required by fish and other pond inhabitants and will cause some low level (unnecessary added) stress. Do you want to do that, then go ahead. Best to weigh risk/benefits using educated* guesses. There are better ways to heat your pond.
I like this G.A.S. model in thinking about how koi deal with stress (cold, toxins, infections etc):

Okay I found this quote from Steve Walker owner of the Advantage Koi Pond Heater and Sacramento Koi
From Koi USA magazine
No copper
“Copper is toxic to koi! At high levels, copper can kill koi. However even at low levels it has been proven to greatly lower their immune system, making them more susceptible to getting sick. Many swimming pool heaters use copper for their heat exchangers because of its ability to transfer heat exceptionally well. When the copper is heated to a high temperature though, it begins to shed copper into the water at a much faster rate than a standard copper water line”
So to conclude wholehouse copper is acceptable for me but naw I ain’t gonna touch that copper heater
.003 is toxic To koi and seems trout have higher tolerance. sodium thio can remove the copper if needed. I was hesitant to post this but figured what do I have to lose.... nothing lol
regardless i would minimize any copper in the system as possible..
funny russ did a 20% flow through after the huge centeur carbon filter. maybe all the details should be disclosed. we know all facts are not there at times lol..carbon filters remove metals right? silly rabbits

No, you are wrong.
Carbon filters are not particularly successful at removing dissolved inorganic contaminants and heavy metals such as minerals, salts, antimony, arsenic, asbestos, barium, beryllium, cadmium, chromium, copper, fluoride, mercury, nickel, nitrates, selenium, sulfate, thallium and other contaminants, which may require a ...

It is also used in cigarette filters. Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds.

My personal thoughts:
Filling from copper pipes is ok as this is generally a one-time affair. The water contacts the copper for a short period of time before entering the pond. Recirculating water through copper pipes on the other hand, especially hot water, I would be more cautious of. In a closed recirculating system, copper ions will get the chance to increase in level over time.
Why not 316L stainless steel? It has poorer heat transfer characteristics, but is readily available in rolls like copper and can still be hand worked at smaller diameters.
There are probably different ways of doing things but the diy copper heat exchangers I have seen circulated hot water in a closed loop internally and cooler pond water circulated on the outside of the coil. The coils had a visible coating on the outside of noncorrosive nature typical of aged copper. This is typically what happens in normal conditions in home copper water pipe and it has been proven this coating is protective in nature and slows the ion transfer. This is why homes with new copper pipe initially have higher levels until the coating builds up. Maybe why people who use them have zero problems.
Not an endorsement of using copper coil heat exchangers but a plausible explanation why no negative effects.
