More of my thousand questions for a new lake completed about 4 weeks ago . It's about half full due to a 60GPM spring, will be about 1+ acre, and will be 20+ ft deep. I've tested the water and it shows 6.2 pH with 0 total alkalinity. Would it be OK to add something for a quick change in those numbers before adding FHM? What should I add and how much? My goal is to stock bluegill later then LMB next spring. How do I know if I should add fertilize?
