 Good question, I would probably start with about 1000-1500ml of Pellets, you would also need to run a larger reactor for this volume of pellets.  From all of the reading I have been doing it has become clear that it is pretty tough to overdose these pellets, supposedly they have a very large safety margin. 
 You would still want to start slow as to not shock your system.  Our Nextreef MR1 XL would be a great reactor, also allowing room for expansion.
