HELP kid dumped bubbles in tank

[Jilly92]

Anyone got a take on how safe this might be?

Those numbers would not be relevant presently. Ive used tap multiple times especially when I was just starting the hobby. I really don't think it will disturb anything. You may get an algae bloom. But if I were in your situation I would use it. Make sure to use a dechlorinator. My 2 year old dumped a bottle of essential oils in our tank once, so I feel you.

Just curious, but why recommend something known to be risky (due to potential for copper) to solve an issue that seems to have resolved itself?
