Way to sanitize hot ponds/check bacterial levels?

[Rob Tucker]

Bring all the bacteria testing gadgets you like but don't consider pouring anything into a public warm pond. You can have your own private warm pond if you buy one but don't go dumping chemicals in it either.

The warm ponds have what is called brackish water. A mixture of sea water and fresh water. Silky. Blissful. Tides raise and lower the levels. Anything you put in the water you are putting into the ocean.
