I put a fish in my qt today and I accidently used the same net I'm my 250g Reef tank right after, should I be worried? The net was a little wet and I just started dosing my qt with copper yesterday. It just happened 30 minutes ago so I couldn't tell you if my invertebrates or corals are affected by it, the net got wet from my QT and I used it again in my DT. first time I use copper so that's why I made this mistake.
