Dino blackout: next step

[Bouldereefer]

Hopefully quick question. I had Dino takeover. I have my theory. Point is I have it. I chose the blackout approach. Once the blackout period is over do you immediately do a water change?

Shouldn't matter. The blackout makes the dinos all get into the water column and a uv light kills them is the theory.

A water change might help with lingering toxins but I don't think it will much matter
