    We have enjoyed giving this service free of charge however ongoing increasing financial costs of running this service is making it increasingly difficult. Up until now we have resisted advertising as a means of a revenue stream to help run this forum but it has become inevitable that extra revenue is required to run this forum.

    To cool my water, I was thinking of using a converted window air conditioner to cool a tub of water and using the cool water as a water bath for my nutrients. I don't have any stainless steel coils readily available but copper coils can be bought relatively easily.

    My question is... Will the copper coils in contact with the nutrients for cooling purposes be harmful for the plant or fish?

    P. S. to Admin: If this thread should be in the fish or water department just move it over.

    It is not desirable but in limited contact you will be OK. I have done similar to that but for heating and it was OK.

    Would it help if I lightly coated the copper with paint (latex maybe?). Although I don't know if the paint itself will be more harmful of the two. hehe.

    Yes, you could make it worse. Just go with the copper. Copper is antibacterial so it will most likely kill bacteria that actually comes in contact with it, but the system should have a very large population of bacteria. But moderation in all things. I would be more inclined to find some stainless if you possibly can, but if you can't do the best you can with what you have.

    Too much heavy metals in the water can hurt the fish by cutting tissue in the gills just be careful

    Thanks for all the input. I got "scared" enough so I decided to insulate my copper from the rest of the system by making the copper cool a stainless container and having the fish tank water travel around the container to cool it down.
