What do you have in the way of snails and crabs or other CuC members?

What test kits do you use for Nitrate and Phosphate? What nutrient export methods (GFO, refugium, etc.) are you currently using to control nitrates and phosphates?

I use Salifert tests kits for phosphate and nitrates, i have a refugium with chaeto used to have GFO but i was striping too much nutrients and my corals were getting affected now with just the refugium and skimmer i have my nitrates at 2.5 but still my phosphates are showing 0.

Its hard for me to tell, but at least from some pictures it looks like a precurser to coralline. Does it rub off easily?

No, not likely. Not if they are out and healthy.

I would add a few more turbo snails as a first effort
