I have a collateral question. I also have very clear water-my pond has very active springs and high turnover rate. I believe my clear water probally is the major contributor to my filamentous algae problem (see posting at "controlling algae" for a more detailed description of my pond). My question is what is the downside of having a clear pond? I enjoy being able to watch the fish and plant life because of the clarity. My bass and bluegills have grown significantly since their introduction 1 1/2 years ago. Will the clarity and lack of fertilization effect the numbers of fish the pond can maintain? the size? If it remains clear are there any other long term negative effects on the fish or ecosystem? I really am not necessarily interested in raising monster fish but would like to have a healthy ecosystem.
