That would be true to an extent. Halimeida does use phosphates in growth, it simply builds more of its structure from calcium than some other algaes.

Edit:

I guess I should answer the thread's question... haha!

I cant select any of those options above. I have tested the phosphates and got a 0 on the kit.. but ofcourse most kits arent the best. My only method of phosphate reduction right now, if there is any, is use of a refugium. I am considering using a VERY small amount of phosban on the next system, but just for the heck of it, the fuge will be huge anyways, and with a low fishload, high floow, good skimming, I dont see it being an issue.
