If there's no LIVE fish in your tank, I don't think you should change the water.
Another person did a similar style of cycling, but she used cocktail shrimp to do it.
Had a sock full of slimy rotten shrimp. They managed to take some pretty sweet pictures to capture the moment. Definitely worth checking out.
I suggested the heater because it definitely helps with bacteria production. I turned my heater up to the max setting which was 89 degrees, but it heated the tank to 95-97 degrees.
- Shrimp & fish food methods are the two stinkiest/grossest methods, but of course I don't think anyone mentioned that.
