Hi Bro,
Thanks for sharing with the community your journey of reefing, and I feel very sorry for your recent loss of livestock due to the power trip.
What impress me is your positive attitude, you bother to share with us about the findings of your copper treatment in great length, that's a great effort
Also, you seems like a humble chap, taking all criticism in good stride, that's quite remarkable. Most of the bros / sis here are mostly very helpful and well meaning and am sure they will be most willing to help if you need any assistance.
Wishing you very best in your next bigger tank project and happy reefing
