Here's a picture of he entrance of the pool/pond. The drain pipe is sticking out. Usually the drains are at the bottom but I want to be able to sweep the bottom of this little play area and have the algae clear out of the water as quickly as possible. Another "keep the peace" with my wife plan. The next photo is of the water fountain area. The whole area will be a play for the kids but also act as a heating area for the water. The next photo is of the bog area. It will be about 1 meter deep and the water will flow up over the retaining wall into the swimming area. The last photo is of the entrance of the pool/pond with the boulders in the background.
