...but I knew nothing about surface aeration such as Kasco and since PondBoss does not allow any posts other than PB advertisers, I felt that I had not been properly advised.
You're kidding, right?
I'm not a Pond Boss advertiser and I've made dozens of posts on aeration, including the one that's archived called "Aeration simplified". I've known Bob Lusk for pushing ten years and he has never, EVER once said that posts can only be made on this forum by advertisers. I would say that a full 95-98 percent of the posts on this forum are not by Pond Boss advertisers. In this case, it is you who is misinforming other members.
Here is a example from 10-02-2005
http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Main=2967&Number=30977#Post30977When you say you were not properly advised, are you implying that it is the "obligation" of the members here to properly advise you, George? Don't blame others for your fish kill. A simple five minute search on my part revealed several posts on using surface agitation to increase DO levels in a pond.
It is YOUR obligation to gather as much information as possible, and make an informed decision.
