Lights out & Clam?

[NanaReefer]

I have a bad case of cyano. Not a parameter issue and all new lamps.
Will my Clam be ok during a 3 day lights out? I've never done this method before so I'm very nervous about it.

Yes. It'll be fine

Just wondering...

How do you know it isn't a water issue? IMO/E, if you don't fix the root cause, it will just come back, lights off or not.

Are you using RO/DI water? If so, what is the TDS?

It should be fine.
