Diesel,
I am not sure of the exact strength, but I am currently using component system 123 and had to increase again today, I am currently doing 220ml per day on my 120 gallon sps reef. I was previously using 2 part from Seachem Reef Fusion. I was dosing less than half, around 80ml of the 2part per day. Now keep in mind, that when I did try BRS 2 part, I was about double of the Seachem Fusion. So it is not as concentrated as other 2 parts I have used, but the impact on the colors of my corals has been noticeable. I hope this helps a bit, the instructions for mixing are mentioned by Michael, as he currently mixes his own balling components. In this thread I think he gave instruction that came with the products. Cheers!
Something doesn't make sense to me. In a 5l jug 220ml a day will only last 22 days. So that's 1050$ a year?
