Fio, I stopped by the Home Depot in Patchogue today and they had about 10 bags of mag flake.
Chris, i have started using the two part, i've been doing 3 pumps of each every morning, but i'm still trying to get my calcium up so i've been testing and adjusting in the afternoon. I'm hoping once i get my numbers were they should be the 3 ounces of each daily will be good because i'm also topping off with kalk.
