I have read so many wonderful things here my head is spinning. I need help knowing two things right now. I will bookmark them so I wont have to ask my questions again!

First, euthinasia. I liked the article vety much. Its the hardest thing to do. I want to find the chemical suggested.

Second, water cleansers and beneficial bacteria for water that outcompetes bad bacteria and nakes the pond more healthy.
Thank you all very much!
