I have a 4500 gallon Kayak pool and I've had a small leak from the skimmer hose connection which I believe I have rectified yesterday. The amount of leak doesn't seem to account for the drop in water level I have encountered since I opened in May. I'd say I needed to fill up about once a week. I know we lose some water from kids splashing. I live in the Philadelphia area and I'm curious how much I should attribute the drop in water level to evaporation. The pool is in direct sun during the daylight hours.
