I recently purchased a ap rack that hold 10 (12qt) tubs and has back heat instead of belly heat. I love this rack but here is the dilemma my house is at about 70 71 degrees and when i went to see what one of the tubs temp out at it was only 82 degrees in the back and pretty chilly still in the front of the tub. I have my ranco set at 98 and i dont know what to do to get the heat up do i up the ranco to 100 or higher... I also put some of that stuff over the window to keep out the cold it seems like it works but i have tryed to insulate this room as best i can I am in a apt so the heat stays in relatively good.

Also in this ap rack since its a all black rack do the bp need a hide in there or will they be fine with out one.

next on bhb he uses a substrate almost looks like mulch what is he using or do you guys recommend newspaper i dont like newspaper because i feel that is partially the reason im losing heat and the mulch substrate would be able to keep in some heat. ADVICE?????

sorry for so many questions let me know
