Hi,

First off, please read these theads if you haven't already...........

Okay,

1. A measuring spoon works well for me. Got mine at the supermarket for a small set of plastic ones for 2 or 3 dollars. Range from 1/4 tsp to 2 tsp.

2. You can drop the K2S04, as the KN03 will provide sufficient N.

3. I do not use Csmb but here is my schedule and works well at 2.5 wpg for a 180 gal tank:

Main Fert
3.00 TSP KN03, 1.00 TSP KH2P04

Trace
50 ML TMG or flourish
Prime at WC for dechlorinization.

+/- 3.0 tsp KN03 3x a week (N)
+/- 1.0 tsp KH2P04 3x a week (P)
+/- 50 ml Trace 3x a week. I use tropica aqua products or others use Flourish.
60-70% weekly water change with Prime

Sunday - water change Main Fert
Monday - Trace
Tuesday - Main Fert
Wednesday - Trace
Thursday - Main Fert
Friday - Trace
Saturday - Rest & Enjoy!

Since you have only 20 gallons less than me, take off a corresponding percentage...

Hope this helps........EI is not as hard as you think. I just started it 6-8 weeks ago and is pretty easy..........
