Review on Fluval Sea Magnesium Aquarium 8 Ounce by Brenda Naple

THAT LOOKS! To be honest this was the first time I had such a hard time with MG in my reef tank. I bought it. I followed the instructions for the first two weeks and NOTHING, the MG kept falling. I spoke to my fish shop and they told me to double the frequency. I did, another week and NOTHING. Then I bought: http://www.amazon.com/Red-Sea-Foundation-Magnesium-Supplement-C/dp/B00BS96CHM/ref=pd_bxgy_petsupplies_img_z and the problem was solved within 1 week, the dose seems much higher and to be higher daily but it worked!
