does anyone know where i can test my well water for what chemicals are in there? i doubt a pool shop can help other than tell me the ph and choline content which i can do myself.

also i'm not looking for microbial stuff since i doubt i have any in a 12m deep well. i did see this thread http://www.thaivisa.com/forum/topic/528141-getting-household-water-tested but nothing in there about chemical tests.

i ask because all my pond fish died recently, and because we recently got an RO machine for drinking water so i want to test what's coming out of that also

thx steve

Pond fish dying can also be because of something else, like a fungus.

Well water does not have enough dissolved oxygen for fish. You may need a pond aerator.
