True friends just call me Larkin
As has been said most don't recommend using stone to cover the liner but there are also those that strongly believe in the use of them. Very mixed opinion. As you have now read the drawbacks I would also recommend doing some research and find information from those that do recommend them.
I do use rocks in the bottom, But I have my own personal reasons and way. I prefer to use flat rock, It covers the liner and gives a more natural appearance, Protects the liber from UV rays, and actually the pond runs a few degrees cooler during the summer. I do lift my rocks a few times a year to blow out anything that has gotten under them, and I have them just a single layer so they don't take up so much of the pond space. I also have a high turn over rate in my pond, I turn over my pond 1 time by a pump in the pond that runs a small water fall and sends water to the far end and sends it back toward the skimmer and filter pick-up to make sure everything is moving to the deep end and gets filtered out, I also run a pump that runs the fliter that turns the water over another time and a half. So the water in the pond does have some current and is always very oxygenated. I do agree with the post above though, If your not wanting to be in the pond doing this kind of maintance, doing without them does make life a little more simple.
