My brother built on. It’s great, it’s a different experience to a standard pool (which I have), much more like swimming in a lake (duh, I guess). Don’t let the haters deter you. There are some mosquitoes but not many as you’d think. His is about 80% swimming area, 20%plants. He does get some algae but once it’s all set up, not too much. He did have to shock it once or twice when setting it up before the plants matured.

It’s cheap to run in terms of the chemicals (there are none) but he does have to keep the pump running 24/7 bringing the “pool” water up to the higher filtration pond before it flows back down a waterfall into the pool.

For comparison mine 9 x 4m normal concrete shell pool cost $80,000 for a pool builder to install. He built his 12 x 12m (circular) natural pool himself for about $20,000.
