No, haven't started copper, was waiting on your advice as wether or not to do it. I am using my refractometer.
Question now that I think about it...when I have to maintain the sg at .09 for 3 weeks, does anyone know how much of the normal 1/2 cup of salt to use to get it close? I brought my buckets out and am getting ready to make them, of course I can just inch it slowly to where it needs to be, that will just take more time.
All fish are alive, and the Tang looks normal - though I know he just must be in another stage of ich. Just hoping everyone pulls through.
Thanks for everything, I'll be around as usual
