Loving how the tank is coming along TLH, can't waitg to see so some more photos once its grown in a little. Should look great 
With regards to dosing, it's probably best to go read Ceg's wonderful thread on EI dosing in the tutorials section EI DOSING USING DRY SALTS
It's a great read, but may take you a few reads before you get your head round it. The post has a section where it tells you the mixture for a 20 gallon tank. You just need to change the mixture accordingly to your tank size. Further in the thread there's a link to a handy utilty called Nutricalc which when you enter your tank details into it, it will work out the dosing for you
