Just moved in with my girlfriend and to save some money she is getting rid of her gardener/pool guy which she was paying $250 a month. I don't know the first thing about pools since where I grew up pools were a luxury for the rich and most everyone just went to the local lakes. The pool is was built with with the house in 1980. So far I can manage to turn the Jacuzzi on along with the heat. The rest of the dials and valves are a mystery and so far all have managed to do is drain the jacuzzi into the pool which I couldn't figure out how to reverse it. Beyond that I need recommendations on a test kit for the pool preferably one that is digital so I have more accurate readings. Another issue is the pool light which I was told needs replaced can anyone recommend a good light to take its place?
