For a third party opinion...you need an alkalinity buffer of one brand or another for your reef tank. It's a must have. Same with calcium and magnesium, and corresponding test kits. =] Personally, my brand preference is Seachem for alkainity buffers. This is a great product. I would buy it from him myself if he was here in S'toon. =]
