We did just that. I bought a small above ground pool for the kids last summer (15' diameter) and our yard wasn't level. Digging in the red clay proved impossible so we decided that instead of trying to lower the high end we'd raise the low end with sand. We bought mortar sand, not play sand, and spread it in the area that needed to be raised. Once you add water to the sand it stays in place very well. So well, in fact, that even after the pool was taken down the sand still stayed in place for months. The pool held up the entire summer but the cost of the sand was about as much as I spent on the pool (about $200).
It depends on what you mean by low. You need to check your filter's manual, and see what level it SHOULD be. Lower than that, usually means you are losing sand into the pool (you'll know!) or when you backwash (because the pump is too big for the filter.) If you are losing sand, you need to correct the cause and then add more sand, after you've resolved the problem.
make sure chlorine is is at 1-3ppm, if pH is very low raise chlorine slightly higer than average. shock the pool after and run filter for over night. If pool still not stabilize then add PH high chemical.
Check if you have any stabilizer in your pool without stabilizes (cyanuric acid) the chlorine use is greatly increased.
You will want to lay the sand out at 17' x 44' x 3". Give yourself an extra 1ft of wiggle room minimal per side. That puts us just under 7 cu yards of sand. Call it 9.5 tonnes of sand or 7.5 yards. Use any extra to fill in low spots.
You would be safest using Baquacil pH Increaser, which is a high purity, highly active dry alkaline product used to raise pool pH. In non-Baquacil pool water, both Soda Ash and Hydrochloric acid are used to raise pH levels. Pool shops are a good place to seek advice also.
The answer is largely dependent on the total alkalinity (T/A). High T/A requires more soda ash to raise pH a given amount as opposed to a low pH.
You can raise the alkaline level if your pool water by adding sodium bicarbonate (aka baking soda). It is recommended that you raise the alkaline in small increments because it is easier to raise your total alkaline levels slightly if its a little too high or too low. This chart from swimming-pool-care.com gives out how much sodium bicarbonate to add.Desired increase in PPM1,000 gallons5,000 gallons10,000 gallons20,000 gallons50,000 gallons100,000 gallons10 ppm2.24oz11.2oz1.40lbs2.80lbs7.00lbs14.00lbs20 ppm4.48oz1.402.80lbs5.60lbs14.0lbs28lbs30 ppm6.72oz2.10lbs4.20lbs8.41lbs21lbs42lbs40 ppm8.97oz2.80lbs5.60lbs11.2lbs28lbs56lbs50 ppm11.2 oz3.50lbs7lbs14lbs35lbs70lbs60 ppm13.4 oz4.20lbs8.41lbs16.8lbs42lbs84.1lbs
you have to raise the car up. its underneath the ac compressor it shelf
Let me put a comparison. Imagine that you have a kids pool with lots of colorful plastic balls. Then you decide to dive in the pool but you just 'lay down' on the surface. You realize that it's boring so you decide to move. With each move you transmit movement to the balls in the lower side of the pool pushing aside the balls from the lower side to the upper side thus sinking. that's exactly how quicksand works and they tell you not to move or you will sink.
High specific heat capacity, because it takes a significant amount of heat energy to raise the temperature of sand during the day, and that heat is released slowly at night, resulting in the temperature drop.
To fix an unlevel 16x32 pool, start by draining the water to prevent further damage. Next, identify the low spots around the pool's perimeter and excavate the soil underneath to create a level base. Use sand or gravel to fill any low areas, compacting it firmly to ensure stability. Finally, refill the pool and check for levelness, making any necessary adjustments before adding water back in.
To fix low spots in your lawn, you can add topsoil or a mixture of soil and sand to raise the level of the low areas. Spread the soil evenly and then compact it gently to create a smooth surface. Water the area thoroughly to help the soil settle.
