Hey guys so I had another ich outbreak I’ve decided to go from ich management to ich eradication once and for all!!! Here are some pics please let me know if this is regular ich or black ich or a mixture I do notice some darker spots on the sailfin tang...also please advise on how to use copper haven’t used it yet cuz I know it can be sketchy so I’m waiting for the fish to settle down since they’ve just been transferred into the QT...also sailfin tang is the only one showing spots as well as a clown but they have been eating really well which is good...so please shoot your advice thanks
