Don't mean to jack the thread MMAX this might just help us both.

Provided the variation in temperature is a result from the heaters (tank temp falls below set point) you should either combine both heaters with a single controller or upgrade to a single larger unit. I see little point in using two small units instead of the correct size, if you want a backup heater then you need two units, each large enough to handle the tank volume or a large primary and a smaller backup. But really unless you pay little attention to your tank you'll notice a heater failure before livestock is overly effected (especially large volume systems), quality and correct sizing is your best protection.
