Just purchased a home last week with a nice 30' X 15' kidney shaped pool. I have never owned a pool before and know absolutely nothing about maintenance. I have read up some on here and talking to people that at the pool shop nearby. Pool was in really good condition. Luckily, I just had to add some calcium and some hardness control and the pool was ready to go. I live in texas so using the pool at night is great. Still hot enough outside for it to not feel cold. It has a light on the pool. My problem is I have absolutely no idea how to turn it on. It is an underwater light. I don't know if they bulb is out? Is it supposed to turn on when I turn on the pump? Any advice where to look is greatly appreciated. I will continue to educate myself with the help of TFP. I plan on getting the test kit soon so I don't have to make the trip to pool shop with my little water bottle of pool water. haha
