Copper:

Any amount of copper is unhealthy for any fish, and copper is usually only used to treat copper sensitive parasites. Any amount whatsoever is bad.
0.05ppm will irritate loaches IME, 0.1 severely irritates them, anything over 0.2/0.3 and they completely lose it and start banging into things, whipping around.


Chlorine:

Again you want absolutely zero. Of course, there is a tiny bit in the water even after dechlor but with good aeration this leaves your tank pretty fast.
Ideally you should totally dechlor (let water sit a day) THEN add it.

If you have copper in your tap water you have a couple of options

1: Dont use tap water

2: an R/O unit and/ or a deionizer (anion/canion resins) to run your tap water through, or you could run this through a tubularly shaped filter like a whisper i or a canister in a media bag in your 'gas out' bucket.

If you use both R/O and deionizer this will give you about 99% pure water, and you will need to reionize and remineralize it with something like Kent RO right as well as a kH boosting agent.

3: cation resin (ie, KENT Toxic metal sponge) this is a better option since it specifically targets metals.
