I recently acquired a beachfront property in tropical Thailand with a swimming pool made of plaster. The pool is only 1 year old, and yet I already see some pop offs on the plaster surface. Furthermore, the pool has been filled using ocean water!
When I spoke to the former owners, they told me that during the time they were building the pool, they couldn't secure fresh water to fill up the pool (as the property is in a remote island). So they decided to pump ocean water into the pool. And they have not replaced the water with fresh water since then. The water though is quite clear -- they have managed to filter it really well. But tastes a bit salty of course!
So my question is, could using the ocean water in a swimming pool that is built to hold only fresh water adversely affect the pool plaster and cause the pop offs?
