Excel and Trace mix with EI

[JeffHerr]

Quick confirmation request...

55Gal heavily planted tank
Metracide carbon supplementing, no CO2

I'm making up a daily mix for Excel+Trace:
450ml Metracide
1 tsp CSM+b
1/3 tsp Addn'l Iron

Dosing the mix at 15 mL / day (at least 12 hours apart from Macros)

Based on 450ml = 30 days (4 weeks) of 15 ml/day
4 wks * (1/8 tsp CSM+B twice/week) = 1 tsp CSM+B
4 wks * (1/12 tsp Iron per week) = 1/3 tsp Iron

Sound right? BTW, I know the Glut is high, but that's on the recommendation from Tom Barr. And I don't question Tom Barr!
