yes, that would be your best bet. you can use bleach solution on the tank itself and any decor, bowls, etc. just rinse very well so there is no bleach smell. wash the plants and wipe them down with chlorhexadine/nolvalsan. also make sure to use an organic soil, or one with no additives or fertilizers.

i'd like to see some pics once its all setup and housing the gargoyles too!
