Can I blackout refugium?

[jjencek]

I had an outbreak of dino in my DT. I was able to get it under control by lowering the light to 2 hours per day and running UV.

Now the DT is fine, but I do have an outbreak in my sump where I have my refugium using chaeto. I ran the lights there for 8 hrs every day.

The question is ... Can I turn off the lights in my refugium for say 3 days without killing the chaeto?

absolute worst case, you MIGHT see a little bit of die-off, but I wouldn't sweat it. I'm sure you'll be fine.

Depending on how much you have, maybe just put the chaeto in a 5 gal bucket with a light and a powerhead?

That would defeat the exercise - I am trying to blackout the chaeto so the dino on it dies.

In that case I would say you are fine with a 3 day blackout. I keep chaeto in my DT and a three day blackout in my DT didn't kill it.

Just to follow up ...

I have done 3 days without lights in the refugium - dino is gone and the chaeto looks fine.
