Question, I've got a half acre pond that has NO vegetation whatsoever in it. It also has no large fish as they all died in this years drought in Texas. Its filled to the brim now and has covered over lots of rye grass and weeds that started growing in the dirt pit that was once a pond. Would this be enough to get them going and keep them going? The pond does have a large algae bloom in the spring but for about 4 months and then it dies down.
