They aren't toxic. They are not even as strong as many household things you might clean sinks, drains or toilets with and wash down the drain. One exception might be one of the Salt test reagents. Do you have a salt test kit?

Edit to add: When you test, you pour out the samples somewhere, so unless it's in the pool... Same place.
