A few hours ago I came home to see a almost 100% meltdown of the tank.
Somehow the light switch didn't work, leaving my lights ON for two days. This caused the pH to rise so high, that precipitation of calciumcarbonate shut down almost all of my pumps. 3 out of 4 Tunze Streams and the return pump.
This was too much for most of the corals. 25% are already dead, 50% is dying and the rest is severely stressed.
The tunze are now soaking in vinegar but I think they're not fixable. The shaft is unmovable, completely stuck.
I don't now what I will do now, stop or make a restart. I'll keep you posted.
