Diatoms after the cycle, what would you do?

[Van Eternal]

Hi reefers,
Tank has recently finished cycling and diatoms started forming on the side of the tank that gets a little sunlight. I have my lights off. As expected nitrates are relatively high after the cycle (i used marco rock and live sand) I am planning on doing a larger wc before adding any livestock. Hopefully to reduce the nitrates to some extent. Is it a good moment to start a refugium ?

Should i brush off the diatoms from the rock using a tooth brush and siphon the sand ? Or wait it out and let it die off ?

I wouldn't do anything. Algae is normal thing.

Same as @Jekyl, I embrace the algae. I only control what might actually harm my live stock (i.e. because of smothering or whatever).

But I do understand some people want to have way more control over the algae by trying to eliminate them completely. I can't help with that though because that's not what I do. XD
