BarO :

Do not feel alone . Others including me have made similar mistakes . I learned that high copper content in a low alkalinity situation can cause the BG to not be able to uptake o2 . Apparently the process does not reduce the o2 level but only the ability of the BG and bass to make use of the avalible o2.

As Meadowlark suggests it is the journey that is important and I agree. Do not be discouraged keep on . You may want to check out the Texas Cooperative Extension Service on line for its publication on management of recreational fish ponds. Good Luck --ewest
