I totally forgot to introduce myself - just bumped in and started loading questions on you 
I am F, 46 and living in Denmark with my SO and 3 sons (11, 17 and 19)
Being from Scandinavia, we don't have a large pool tradition here. When I grew up, only "the rich ones" had pools. Always IG, typically 8-shaped.
The rest of us got a new paddling pool for the garden every summer.
As the years have passed, pools have become more common, but mostly Intex-type. 95% of all owners empty them each fall and store them in the shed.
And 98% maintain them by "dump and pray", following test strips and guides saying 1-3 ppm FC.
I was one of them until last summer, when I discovered TFP.
I don't have access to the correct testing kits, so I go by my photometer and common sense........
