I currently own but one single BP, however I am thinking of expanding over the next few years. Here is a husbandry question for you rack/tub type users....

Most of the questions posted here refer to people's tank setups, regarding temperature gradient etc.... However when people show pics of their racks, there is usually only one hide, and no thermometers....

What is the science of setting these racks up correctly? I know there must be some way to do it correctly, maybe even the same as I use with my tank, who knows... But all the big shot breeders and such use the racks, so there must be somthing...

Thanks for the info!
