With 60 gpm coming in you should reach full pool in short order unless you have a leak. You are gaining roughly 600,000 gallons per week while an acre foot of water is roughly 325,000gallons. What I'm trying to say is that you will have heavy outflow once full pool is reached, fertilizing sounds like quite a challenge even with aeration. I would let the pond fill and reevaluate next spring.

By all means add FHM and CNBG now...you may still get a few spawns before temps drop too low. (With a spring like you have, I would have added FHM at about the 2 foot depth mark.)

Also, add a feeder too!
