Thanks, i read Erica Strauss and had a look at the butler swimming pond dvd and listened to Paul weathon podcast but what i am worried about, is getting a clay or mud mask every time we go swimming, and the idea of a plastic liner disintegrating in the water is annoying me too.
I think i will turn to the first idea i had, more expensive, not as sustainable
as i wanted it to be ...we will dig and seal with concrete
, cover it with flat rocks, tiles like, the rocks will heat the pool when it is sunny i think, we will put a lower bubbler to circulate water on the deep plunge side and a pump
to eject the water through the surrounding gravel and plants area, so the only "eco" aspect of the swimming pond will be the solar
powered pump and bubbler and the filtering through the regeneration area instead of chemicals added to the water.
This way we get the best from both world, what do you guys think?
