Vincent (my betta) hasn't been doing so well these last couple days. He's very old, and he has a tumor, and I think he's going to pass away in a few days. I really need to do a water change, but I'm afraid that doing taking him out of his tank to do a 100% water change will stress him and kill him. The only thing i have that's big enough to do a 50-75% water change is a gallon pitcher that we sometimes use for drinking water.
So, basically I'm asking,
1.)Is betta water conditioner is harmful to humans?
2.) Will it be fine to use it if I wash the pitcher out really well before and afterwards and then put it in the dishwasher??
I'm NOT going to put the dirty fishwater in the pitcher, i have a small glad-ware container that i use to scoop it out (used for water changes only). I don't have anything else big enough to put the new conditioned water in before i put it in the tank, so i hope its safe to use it
