Disinfecting new tank & decor

[Mentat]

Hi Katy! I've used vinegar to clean tanks that had calcium deposits or watermarks on glass. If tank just needs disinfecting, then use a 10% bleach solution in new sponge. Leave it in contact for 10 minutes, rinse thoroughly, prepare 4X dechlorinator solution and apply with sponge, then rinse again and let air dry overnight .
