Warmer weather tank questions

[Slick Fork]

An extra heater won't make your tank any warmer, and removing one won't make it any cooler.

two heaters will just influence the maximum possible temperature and how fast it can get there. If they're both set to 77 and your tank hits 81 neither heater is doing any work. I'd leave them both in and not worry about it.

Also, no discussion of heaters would be complete without a warning to have them on a reliable temperature controller!
