So i had to do a water change and i only had one more pump that was running in my QT. The qt is fishless right now but i completely forgot there was still copper in the water. I used that pump to mix my water that goes in my main tank. I immediately put carbon in the sump of my main tank to remove it tho.
Is this going to be a fatal mistake for my corals ?
