125g tank.
In July of 2021 I converted this tank from freshwater Oscar’s to saltwater. I haven’t had any success since then.
Lost quite a few fish due to aggression in the tank. Lost a couple when my media bag ripped and purigen media made it into the display tank. Lost a few fish when my LFS told me a trigger fish would fit in a community tank. Most recently lost most of my tank to flukes.
I’ve tried adding corals about 4 times over the last 10 months. Not a single one even opened up. No one could figure out why…
3 weeks ago I took out the rock, drained the tank and moved my remaining fish to a QT set up. Put my rocks into a brute trash can with a pump and scrubbed my tank out after draining. I started to clean my sump and noticed that my fittings were blue….and then it hit me. I didn’t replace my brass fittings when I converted the tank over. They had been leaching copper/zinc/nickel into my tank for the entire time.
So this is my restarted tank. Almost a year later. Any of you guys made such a silly mistake?
