supplements in large tanks

[gemz]

hey guys...I only have a 37 reef right now so i dose with kent part a&b...will be switching my 110 over some day and so i was just wondering what you guys with large reef systems use to supplement your tank? what would you suggest and maybe some cheaper alternatives you may use to supplement?

I use a home made 2 part, actually 3 part as I test for and dose magnesium. I believe B-ionic is the best, but it gets real pricey when dosing 2 cups of each part a day.
