Ok so what is the best and or easiest way to dose magnesium. Let's not forget cheapest.... I am currently using Red Sea reef foundation but I have a big tank and well it's not cheep. I thought about adding mag to my Ca reactor but that is running really well and don't want to mess with it. I am thinking about Epsom salts but haven't found quite the info I need to say yay or nay on that one. What do you thing and or use and why?
