Hello; You lost me again. You use well water. Most well water does not have treatment chemicals such as chlorine or chloramine in the water.
I had a well at one home years ago. I used the water straight from the well into my tanks with no treatment. I also drank the well water. I know there are folks who use the Prime in well water but if the well water is good water I do not see why. If you have bad well water then I doubt the Prime will fix it.
I am now on "city" water with chlorine only. I have to store my tank water for days in containers or use Prime. I would like to have a good well again.
Well water in indonesia is not safe to drink. I live in riau province where clean water is even an issue. I dont know any professionals who can test my well water. Eventho there is no cholrine in my tap water, but it contains some ammonia, so prime does have a use in my case, i suppose?.
Different story with water in the usa. I used to live in colorado for 5 years, wherr the tap water is fine for drinking.
Years ago, i used well water directly to the tank for water change and my fishes kept dying one by one. So i gave up with fish keeping.
About 7months ago, my 3 years son asked for a small tank, and he got it. This basically what drives me to where i am now. His oscars are still alive after i understand fish keeping is all about taking care of good water, the fish will follows.
