The simple answer to this question is yes, of course, you can recycle negative edge pools. In our industry, we regularly get asked if we can recycle all surfaces of pools, sizes of pools and colors of pools and the answer is typically yes. The one common theme is if the water is hard and full of calcium and other hardness minerals….it should be recycled. In the Southwest U.S., the fill water is loaded with calcium and other hardness minerals causing calcium staining on the tile line, the liner of the swimming pool and the equipment. In the case of negative edge pools, since the water is constantly spilling over the presence of white calcium staining is even more apparent and typically an eyesore. We recently recycled at 20,000-gallon negative edge pool and here are the results:

Chemistry of the water before treatment

Calcium Hardness – 720ppm

Total Dissolved Solids – 3405ppm

CYA – 100 plus

After recycling this swimming pool with our mobile filtration process for 14 hours we left the swimming with the following chemistry and conserved about 16,500 gallons.

Calcium Hardness – 180ppm

Total Dissolved Solids – 885ppm

CYA – 20ppm

This process is not only environmentally friendly but it also takes less time than a standard drain and refill and is much safer for the swimming pool. If you’re curious as to how this process is done, you can watch the following video.
