What is the definition of a tank crash?

[Wayne]

How about stray voltage? Do I need an analog voltage meter to check for that?

[cwatkins]

Anything metal like fall in to the tank or sump? Screw or something else?

If you have a brown algae on your zoas... it is most likely a cyano. Use a turkey baster to clean them off and they will be fine.

As for the issues... wow. Keep monitoring.

As for a huge water change the day after a huge water change... be careful. To do an almost 100% water change in two days may also be detrimental.

Good luck Wayne.

I only did a 10% water change today and I did pull my zoa's out. LPS is looking better, mushrooms look ok, and only one leather isn't doing good. SPS is 90% dead (just a few small frags, once I get this sorted out anyone got some monti cap they don't want?)

So all in all its not bad, but certainly not right! I have shut my return pump off to isolate the two tanks hoping that if I do have stray voltage its in the sump... Going to get a meter today

Not that I know of... I noticed the brass on one of my pumps is a pinky color where the hose was sitting...
