Consider first using RES and/or HBG instead of BG. Then when the need or desire arises (usually after 5-8yrs) add the BG. SMB will overall do and thrive much 'better' without BG and you will have fewer management problems if you first start or begin without BG. Add them later if not satisfied with results of RES-HBG.
If you haven't read through this topic, check it out for examples of what HBG can be in a pond fishery that is fed pellets.
