Good pump for the pool of the same brand that I bought, measuring 200x300x55, it did its job very well this summer, I ran it every three hours all day from morning when the sun came out until late at night, it doesn't need more hours just enough to recycle the water so it doesn't stay stagnant and catch bacteria. Of course, I also used chlorine tablets as well as an antibacterial liquid that I added every three days about 60 grams at a time. You can get chlorine tablets and this liquid from a store that deals with pools to give you the right ratio you need for your pool, they don't cost much, I got both for 25 euros and I comfortably managed all summer.
