I'm in second phase of Flux Rx for Valonia. That's 4x dose for bryopsis. Took out cuttings of all my macros and have them in the 10g for backup.My Fuge is an in-tank Fuge so the Urchins can get in if they were so inclined. I have 0 turbos currently - they've never lasted long for me.
I've got that weird invasive micro Ulva growing in there currently but a lot of it disappeared when I dosed the tank with Flux Rx. Luckily it was the stuff in the DT that disappeared. There's still some in the Fuge but I'm not overly excited about that since the fish and CUC didn't seem to touch it and it was starting to encroach on my Acros.
Botry, Valonia, Caulerpa and yes, that horrible micro ulva all died. Week 4 or 5 right now. Codium is just starting to wither at the ends--that stuff is resilient. That micro ulva is the worst. Completely smothered my Galaxaura, which was an awesome macro, and began growing on my SPS.
My tux urchin loved Botrycladia. Would wear it and eat it.
