Yes barebottom and I am in process of making a turf scrubber. 2 weeks ago when i checked my phosphates where .34 ppm - i cant find any sponge life on my LR, it all died. I am fine with phosphates aslong as it doesnt lead to uncontrolled hair algae, which in my display shouldnt be an issue given the large volume of tangsMaybe you mentioned this already but are you planning on going bare bottom? And do you have a refugium or plan to have one?
Alright, now time to start growing some coral.
