Is it okay to clean an empty aquarium with bleach? It's going to be empty for more than a month and the bleach will only be in it for a day or so. I just resealed the tank about 2 weeks ago so the silicon is still new but cured.
I always use diluted bleach on aquariums and soaking supplies in it. Just remember to rinse well and then soak in dechlorinated water (like Prime) to neutralize any bleach residue.
