I took several canoe trips around the pond this past weekend and have not measured it but would bet with perfect conditions I can see with out polorized glasses down at least 8 ft. I also can see that the vegitation is emerging from as far down as I can see. I have been reading some on the lime and fertilizer to grow algea. Would any one suggest doing this or will that happen naturally? I have also read suggestions of 20% of pond should be weeds. Is this surface area, or a total body of water figure?

Last question, Is Roundup a product that can be used to spray on emergent vegitation, if it is mixed with a can of Coke to stick it to the plant leaves?

Thanks again for your responces!
