I recently setup a home made rack with flexwatt tape and a Ranco ETC 111000 thermostat. I have found that the 3inch tape runs much hotter than the 4inch tape for starters. I have the thermostat set at 91 degrees F with a 4 degree bracket to work within (keeps the tub temp at about 89-90 for the BP). Is the 4 degree differential OK? Since it is a normal temp room in the house the coolest part of the tub is around 75 degrees. I hope this will be enough to breed these guys. Any thoughts.![]()
