I'm not buying that bit about Ph crumbling plastic. In pool chemicals both Ph increaser and decreaser come in plastic bottles and I've never seen one crumble. Plastic is impervious to ph. What it isn't impervious to is heat. And hoses suffer from extreme heat also. I think what scares me most about the elevated temps is that we have this old mindset that we need a "safety" range. In the old days of 180F engines, we didn't sweat until they reached 210F. That was a long way on the old mechanical temp guages. Now, "green" engines are already set at 195F so there goes half of our "safety" range. After all is said and done, the engine that operates closest to it's thermostat setting will live the longest.
