New Tank

[Caroline Hussey]

In the basement I found a really nice glass tank I'd like to use for my gerbils.  It was a tank my brother used for a Chameleon & then for crickets, so there were a lot of dead crickets in the bottom and other stuff I couldn't identify.  What's best to used to clean the tank? I already washed it out with hot water and I don't see anything left in it, but should I use something like Clorox Spray Cleaner with Bleach?  I'm just not sure if anything would be too strong and hurt the gerbils. 
Also, the tank is really tall, what are the best things I could put in the tank so the gerbils can get the most use out of the space?


Thanks!
