That approach seems to me like using brawn instead of brain. I'll work to figure out what's going in, what's coming out, how the ecosystem is behaving and what's needed to maintain balance. But all with an eye to avoid doing as much actual physical labor as possible. ;-) I didn't get out today, but hope to tomorrow. I'll let you know what happens with the tests and phosphate. I'm looking forward to getting into this over the next week. d ------------------ To unsubscribe from this list, please send mail to majordomo@thekrib.com with "Unsubscribe aga-member" in the body of the message.
