Oil film on top of water....new as of this morning.

[BrentATL]

I have been maintaining my pool for a year now (thanks to TFP and the FT-100 kit) and all has gone darn near perfect. I swam last night and nothing was out of the ordinary, but when I went to check levels this morning, my pool is covered with an oily film. Please see attached photo.

I have a heat pump that is 14 years old and hasn't worked since last summer (no bypass on it). 1.5 hp Hayward pump, SWG, pleated filter and solar heat panels on my roof. No visible leaks around any equipment.

All chemical levels are within recommended range according to my "Pool Math" app.

I top off the pool when needed with well water but have verified there is no oil residue coming from that water source.

Thank you for any direction you can point me.

Any pest or lawn or tree treatments?

Something was dumped / sprayed in the pool.

No lawn/tree treatments (ever). No kids and it's only me that swims. I keep my pool deck spotless (to the point of obsession). I'm in Florida and pool is also caged.

Refrigerant oil from heat pump?

I am going to cut the heat pump out this evening and re-plumb it. I can't think of anything else.

You can purchase oil absorbing pads from the auto parts store or home depot, though not sure if they carry the floating kind. In the marine repair industry, we called them bilge pads, ones that floated and would take up float oil. Might could find some of those at a marine repair store/supply.

Update: I removed the heat pump yesterday and today the water is 98% oil free. I didn't see any obvious issues with the heat pump as I tore it completely apart, but it's the only thing that's different today.

Tennis balls work amazing to soak that kinda stuff up. Sunblock oils also.

The heat pump will have a core leak and have lost all the freon and beyond anything serviceable by yourself. Quite possibly will be looking at a replacement HP after 14 years.

My HP did have a freon leak and due to its age and condition, I just pulled it out and will replace it someday....maybe. Only used it twice in the past 18 months so averaging my cost per use for a new unit is very high. lol
