Accidentally spilled methylene blue in tank

[OwlGirlOco]

The tank was empty, thankfully. The bottle cap came off and dumped a ton in the tank. The top layer of sand was dyed blue. Could this harm my axolotls?

it won't harm your axolotls directly but it may damage your biological filtration, monitor your water parameters.
