Pond Boss Forums GENERAL QUESTIONS Water chemistry Do I need to add lime?

I had the City of Bloomington do a limited water analysis. Results: C.O.D. 19
Hardness 62 mg/l
ph 7.6
e-coli 7/100ml

This is a 30 ac. lake, average depth 8 feet and 18 years old.
LMB is the goal. Rain water fed from woods and pasture. No grain farming.

Do I need to add lime above and/or in the lake? Or do I need an alkalinity test first?

Also, is there a list of all the acronyms used on this site. I can get some of them...LMB, SMB, etc... but some are strange. Or could someone make such a list for us dumbies/newbies?

Thanks.
