Could be the change in nitrates (being reduced quickly). My tank is about to it 2 months after the transfer, I used all new sand and added some cured LR. I’m currently dealing with cyano myself, it’s on the sandbed and on the rocks trying to cover corals :angry:

As far as NOPOx goes, I used it in my overstocked 150g and it was a beast in nitrate reduction. The only negative was bacteria clumps in my sump (looked like a yellow/brown slime). I would use a turkey baster and suck it out.

I have used nopox to get rid of cyno, it worked well for me.
Could be your flow isn't strong enough in those areas, cyno likes low flow areas.

Yah, if I were to venture a guess, I'd first tackle the flow. Looks like you have a pair of Apex pumps in there, which would normally be sufficient, but your rockwork is really dense. A couple smaller pumps (Sicce Xtreams, etc) behind the rock would do wonders. That or you could just open up the rockwork.

Also, how is your sump set up? Are there any large piles of detritus?

Nice Candy Basslet btw!
