Natural pools are alternative types of pools that are both inexpensive and environment friendly as compared to any of the conventional swimming pools. For the natural pool plants, there are several options. Aquatic and semi aquatic plants are perfect for natural pools. And also, make sure that you include natural pool plants that regulate high oxygen output such as the submergent types of plants which includes the common waterseed and the hornwort. These types of plants will ensure healthy water. Although you have these beneficial plants, aerating your natural pool is still required on a regular of four to eight hours a day to make sure that the water is oxygenated as this also prevents the water from being stagnant and contaminated.
