In addition, you should separate those leos who are symptomatic - preferably in a different room altogether. If you can't put them in another room, move them far apart physically as possible and have the healthy ones on a higher shelf if you can.
Take care of your healthy leos first and then take care of the others. Use disposeable gloves (shouldn't be more than $8 for a box of 100, and often half that). Don't allow anything - food dishes, etc to go from the sick ones to the clean ones.
Also if you have any leos on the floor move 'em at least a few inches higher... ground level is covered with germs. Green stool can be caused by bacterial infections as well as protazoan .. talk to your vet about what to clean cages with. A mild bleach solution is very effective for almost everything ... but a very few things are resistant to bleach while susceptible to alcohol based disinfectants. Coccidia is one of those.
Good luck to you, jump on it now (as you are doing) and hopefully you'll have it fully contained and treated quickly.
