Background; have old 2 acre lake, restocked last year FHM, CNBG, HBG, LMB. Added a fish feeder. Desire is to catch large BG with nice but not trophy bass.

Did water sample and here are some numbers:
Calcium: 15 PPM
PH: 6.31
Alkalinity: 68
Hardness: 3 (grains CaCO3/gallon)

My question; are any of the above numbers a concern and if so how do I correct it?

I have added a well and it's PH is 6.8. I've been pumping water in so that should improve my ph.

When my feeder goes off the BG crash the surface. I've got FHM all in the shallow grass areas. To me; it looks pretty good. But I'm a novice.

Do I need to do anything?
