Yesterday I got into a discussion on Myspace with a kid from Marrietta who works at Pets Unlimited. He was in favor of the use of bioballs in a reef set-up and had this to say on Nitrates:
"actually it is recommended to have a nitrate level of 10ppm in a reef aquarium, as it helps to dissolve the aragonite so essential trace elements are released into the aquarium."
It was my understanding that a pH above 8.0 helps to dissolve aragonite, and dissolving aragonite has nothing to do with trace elements- it maintains a good buffer/Ca level.
He also had some not-so-nice things to say about the ARC, but he was young (19) and is probably hot-headed. Is there any truth to what he said or is he confused?
