Sand is good because its non-porous & very dense so it won't have absorved
the MB & nor will it have got down into the substrate. Lucky you have sand &
not gravel.
I'd buy all new filter sponges as soon as possible & throw them in your
other tanks to cycle. Better yet put them in the filters in the other tank,
leave the other tank's old filter sponges in the water & then after you've
done the carbon swap out all the filter sponges with the old ones from the
other tanks when you are sure you have removed the MB from the water. If the
filters/sponges are not the same then just put the new sponges in the tank
somewhere near either a filter inlet or outlet & try & get some water
passing over/through them. They'll build bacteria very quickly in a cycled
tank.
In the meantime keep checking the ammonia in the tank that had the MB in it.
As long as that isn't building you have time to cycle new filters & run the
carbon clean up. You could also try some Polyfilter - expensive but works
really well. If you start seeing Ammonia before you are ready to swap the
filters around then see if you can control it with water changes.
