Yep just stick a white sponge in instead. You'll never really need to change these either.
When you've finished treating the tank do as large a water change as you can manage by doing really very thorough gravel vac, as ich goes through its cycle everywhere, including the gravel, not just on the fish.
Water changes will remove the blue.
