You are a weird one. Have you not read anything I wrote.
Lets get a recap.
I stated I used copper in my tank 13-14 years ago. 12 years ago I switched over the FOWLR. This process took a year because I went straight from FW-Brackish-SW without any teardown. From 12 years ago to 6 years ago it was FOWLR. No fish loss, I did return them to the LFS when I went reef. In 2002 I setup the same tank as a reef, this time I tore it down completely and put in live sand/rock, etc.
Show me ANY post that dates from 1996, when I went FOWLR, that states how bad copper is for a SW tank. There isn't any! Had I known at the time what I do now I would have NEVER used my tank.. but that information wasn't available. At the time LFS were selling FW ick meds for SW tanks due to lack of knowledge.
BTW, I have sunk over $13,500 into my tank now, just since going reef.. I keep track. And I spend about 5 mins a day in maint and an hour or 2 watching my tank.
