What's in your tap water

[aquarium]

Huh, I thought this change was mandated by law to go into effect a long time ago. For all the reasons Richard says, it's just a better way to treat tapwater.

If you have any friends with fishtanks, you might warn them. Back when there was a higher frequency of water utilities making this change, the aquarium forums were full of the tragic consequences.

Thanks for the explanation.

Since I fill my water bottles at home from my well we almost never drink city tap water, and the pool gets topped off from me geothermal heat pump water discharge, I really don't care much. Just thought it might affect others.

I will warn my friends with the fish tank.
