Algae only on sandbed, Help!

I would caution you to raise your NO3 and PO4 BEFORE treating with fluconazole. Reason being that dino often times creep in as soon as you treat and kill some other pest. Killing the pest makes room for the dinos. And dino are far harder to get rid of then bryopsis.

One of the most common things seen on the algae threads is, I had cyano or bryopsis, then treated with (insert chemical here), then I ended up with dino everywhere within a few days.

That's a really good tip thank you, I have Dino X if you've ever tried that, battled it many times in the past and Dino X easily does the job within about a week

Yeah that’s bryopsis, the branching/fern look is what makes me think that. I used Flux RX and it completely wiped it out.

Ordered some flux RX, will report back in with the results, thanks for the help!!

I'd look at replenishing your CUC as well. Reef Cleaners has tank size and dimension specific ones that were great for me. Free shipping on the packages btw.
