this web page is very accurate to how to properly cycle a tank... I strongly recommend learning as much from it as you can with a tank that large.
I think she knows to wash the sand already. Also water conditioner is obvious because she is keeping and breeding bettas.
Also its not a chemical to make cycling faster. That would be something like using ammonia to start the cycle. This Seachem Stability adds beneficial BACTERIA to the tank, so you dont have to wait as long. Also many members have used this product with great results. I've said it before Byron added over 100 fish to his 115 gal aquarium in one day after a problem. With no deaths.
The product is to start the cycle for you. So instead of waiting sometimes 3 weeks to finally get an ammonia reading and the bacteria growing in your aquarium, it will start it right away. This doesn't mean its an instant cycle. So you still need to watch your parameters and not put all the fish in the aquarium all at once.
