Water Volume in Above-Ground Pools
The Optimum water level in a pool is determined by the following picture. Pool heights are 52″ and 54″ (48″ being phased out) and your pool is filled to halfway up the skimmer. This provides equal parts of air and water going into your filtration system. Knowing this we can determine the optimum water volume your pool should hold for best filtration/circulation.

Landscaping Around an Above Ground Pool

Landscape rocks or crushed stones are most common around a pool after it’s installed.
They serve two purposes. One is they keep moisture from staying near the pool wall.
Moisture against the pool wall can cause it to rust faster. Second, when spread around the pool perimeter it creates a strong base. Pool and base become one solid structure.
The most used rocks are 3/4″ crushed stones. It can be anything you like. What you don’t want around an above-ground pool is mulch!
The mulch keeps moisture against the wall. It will cause the pool wall to rust quicker.
Peastone Gravel is the Best!

Picture a warm summer day and the kids are in the pool playing ball. What happens every time the kids play ball in the pool? The ball ends up on the outside of the pool.
One of the kids will need to hop out and get it. The Peastone is a small 1/4 inch smooth rock. They feel good on their feet. the last thing you need is for your company to cut their toes while jumping out of the pool.

What Goes underneath an Above-Ground Pool
What is Mason Sand?
Mason Sand comes from larger rocks like granite, trap rock, and or limestone. It’s crushed and then it goes through a screening process. It goes through the screening process twice. By doing this it creates a nice smooth consistency. It feels like beach sand or what we in the business call pool sand.
What is Stone Dust?
Stone dust is a larger rock crushed into dust. Also called Quarry dust is coarser than Mason sand. It packs like concrete and creates a hard pool base. Much like an in-ground pool base. It’s used in concrete construction. A Stone Mason will use for laying pavers.
How Much Material do we need?
These materials come in volumes of yards and or tons. We have a chart that we use to know what amount we’ll need to get for a particular size pool. See the following chart it will show you the amount we order when installing a pool.
