This pond will be moved up against this wall. We have rocks of various sizes that will cover up the cinder blocks. The pond needs a new finish, paint, etc. Any ideas? The patio is decorated in turquoise and white. The rocky area where the pond sits will have an open gazebo , and against the walls on either side of the pond there will be a flower bed about 18" wide with white edged Hosta's and white Astilbe.......
