Ok, whats the best way to improve the water quality? I'm buying a test kit to the test the water and will show you gus the results. I was thinking, maybe I could make a seine to filter what comes in and out of the drains, I really do not know what to do to improve the water quality, When it rains is when I think the pond is hurt the most because thats the time when stuff is coming in and out of the pond through the drain. On the topic of the weed issues, besides removing the cattails, what else do you recomend I should look into doing?
