Tank near A/c

[Jaychevy]

Hey there so I'm looking to set up a innovative marine 30G. The only place I can put the tank for now is near my wall unit A/C. It's not blowing on the tank. The tank is next to it. My question is could I add a second heater to the tank to help with temp drop?

Sure. Many people have 2 heaters in their tank.
