The main difference between a 400 micron and a 500 micron solar pool cover is the thickness of the material. A 500 micron cover is thicker and therefore provides better insulation and heat retention for the pool. It also tends to be more durable and longer-lasting compared to a 400 micron cover. However, a 400 micron cover may be more affordable and easier to handle due to its lighter weight. Ultimately, the choice between the two will depend on the specific needs and preferences of the pool owner. **
