This is my first pool. My only experience with pools is swimming in them. I have a few questions.
The water seems to be going down quickly (1 inch in a week - a few days). I searched about evaporation and it surprised me how much evaporates. But im still not sure. I guess ill do a bucket test. I've only been here a month and ive already added an inch or two, and it rained pretty heavily and added another 1-1.5". Now a week later it seems to be below the level I got it up to with the hose. Its been pretty hot during the day (90-95). The solar heating has been keeping the pool around 85 degrees and there are two small jets. But its florida, its very humid.
Second. What is this hole? Non of the valves turn it on or off. Its on the top step. Is parasol holder??
Third. My pump sight glass is never full. It seems like it was when i moved in a month ago but not now. I greased the o-ring (per the pinch-a-penny guys instructions). Is the pump bad? I keep the filter clean.
Forth. I can not feel any suction from the main pool drain. Is that normal?
