To be honest they stuff I am currently using probably is not harmful in the amounts we the fish in. I only have about 30-40 fish that may come out of there and we will eat it over a 3-9 month time so it may or may not be an issue unless the chemicals in it can build up and never pass through the body.

I am not familiar with this so that is why I am trying to get the info from the brains like yourself and many others on hear that know about this stuff.

I would prefer to just use pond/rain water but that is not an option at my current location.

I have used the following in the past, what problems do you think they pose for fish doomed to consumption?
