Gary, the owner of "GETTANKEDAQUARIUMS.com" stopped by my house yesterday morning and spent a couple hours here discussing salts and supplements. he had some pretty good points. i'm not a chemist, but he did leave me with 4 cases of salt and additives for me, and to hand out when people come over to buy corals.
he was so sure that my system would improve from using his products, that he was willing to give it away for free.
this is more than i can say for any other salt company.

old debate~~ I have used sooo many different salts, and see no real difference, corals always look fine, and i always have to dose somthing within a couple days no matter which i use.
