Poconos - why would my solar cover change colour and dry up in just that area when the contact is so brief it won't do damage? Obviously, there's some damage being done, so one can deduct that if the solar cover gets damaged, so would pool equipment. It may be safer to say "little damage" will happen, but from what I understand some damage will occur - heaters don't like it, so I'm just going to mention it if people ask.
mohawk - You can pour it into the return stream too, however, I think a higher residual will stick around at the wall for a bit since not all of it will get sucked into the stream immediately....either way, it's a very small amount of damage
