Pottsy :

The information I have read indicates that 200ppm is the optimum range for LMB. Don't know what predator fish you have . Like Greg and JM I would love to get to 100ppm , ours with liming gets to 40ppm ,with out lime 10 ppm.

Goldenpond :

As for your question Greg , JM and I will let you have some southern pine trees and red dirt to put in your pond -- guaranted to add acid to your pond. Sorry I can't help more.

Thanks--ewest
