Alright, I've got the plan for my new rack. Melamine, flexwatt, ranco t-stat, and some 28gal sterlites. I am wanting to know how I should do the flexwatt (all options are refering to belly heat). I have a few ideas so just pick what you think would be best and would correctly heat these tubs.

1) Have one tub per shelf with the long side facing outwith one foot of 11" flex at one end.

2) have 2 tubs per shelve with the short sides facing out with 2 feet of 11" flex going across both tubs.

now those are the 2 options for plans that i am considering. It's up to my forum mates (this is where you come in) to alter my plans with whatever you can. Obviously both of these plans can work but i am asking if there are people that have used tubs and how they did it and how well it worked for them. Altering the plans can be something like using 3" flex some way or adding back heat. Any help is welcome. THANKS!!!
