I just got my first 10 gallon freshwater setup kit. I've gone through the steps and been patient (no fish added yet- 36 hours in). Everything is going well except the water temp is hovering at 76F. I do not have a heater nor fancy lights, just room temp tapwater and the lights the set came with. At this point I don't plan on doing the tropical fish thing but it seems that 76 degrees is a bit high.

Any tips before I put in the guppies would be appreciated!

Cheers.
