Thought it might be a neat topic. I am using the Brightwell MB7 and Biofuel along with potassium, iron, and vit c. I take care of mg,alk,ca with the BRS products. Things are good and I am only at 2ppm Nitrate after a mini cycle I am sure from operation low tide. Nothing is any worse for the wear as far as the corals that survived that rediculous ordeal.
I dose 30ml Calcium and Alk 3 times a day along with 30 mlmag once a day. I dose 5ml of vit c, 10ml of potassium, and 10 ml of iron daily. The MB7 is at 6ml a day as is the bio-fuel. I have this all set up on a profilux doser to make it easier on myself.
