I use mine in the winter as I keep a woodstove in my kitchen for extra heat. Keeps us toasty, but makes the house super dry. Smulkin's not kiddin about the pump size, I keep my bp in a 30 gal and the pump is rated for up to 60. When it comes to the pump, the bigger the better. The reservoir can be anything, I like to change them once in a while as new and better bottle types become available in the house.
