!!!!??? It's happening again!

[asylumdown]

My corals are dying again and this time I have zero explanation for it. Everything was recovering from the carnage in February/March, the system was dialled back in, Everything that survived had healed over and was starting to send out new growth tips and then 2 days ago BAM!

Every single coral that had been losing tissue before is losing tissue again. It's starting at the growth tips, so basically all the recovery they've made since I spent 10 days doing water changes, and two weeks testing the water every single day vanished in 48 hours.

This time I've literally changed nothing. No equipment has changed, no chemicals have changed, nothing about the pellet reactor has changed (it's still got 10% of the pellets in it recommended for a system my size), I'm still on the same pale of salt I was using after everything started growing again. I literally haven't touched the tank in two weeks.

I'm so beyond ready to rip this thing out and turn it in to a closet.

Does anyone in Calgary have a recommendation for a lab to do a full work-up on my water? They only thing I can think is that something is poisoning my corals. I've gone over all my equipment but maybe I'm missing something that's leaching copper or something in to my water?

I'm ready to give up.
