heaters and powerheads

For a 40 gallon tank, would it be better to get two samller heaters and powerheads rather than just one larger one? ive read this is a good idea for "larger tanks." but i didnt know about a 40g

yes. if one fails, you have a built in backup. Also, Maxijet 900's use a lot less power than maxijet 1200's (for example.)

This holds true more for the heater aspect than the power heads. A heater is more likely to fail and actually cause harm to the fish. A power head if it fails is not a big deal, so go with two heaters if you can, but the power heads are more of a personal preference... Also depends what other water motion you have, you may not need more caotic water movement.
