Step 9Now place your larger rocks in the main area

I tried to place the rocks so that they encircle the water area and tapered them off so that it appeared that the smaller rocks were at the edges. You might be able to see this in some of the pictures taken from a higher distance. Now the mistake we made which didn't really turn into a mistake as it was a plus in our situation. Here is Manitoba we get a lot of mosquities that breed in standing water. As we used the bubble wrap and the plastic sheeting there is a slow leak in our pond. Why is this a plus? No standing water for breeding insects and no bad smell for stagnant water. Also with a large dog he tends to enjoy laying in our pond on warm days.

The system is really nice and allows you to create something ultra-natural looking.
