It takes a few weeks to cycle a tank, not hours. You need a source of ammonia to get it started too.
Was just about to say the same thing Apocalypse.
I am using the 'shrimp in' method to cycle my tank, also using Nutrafin Cycle to give it a kick start. I started my cycle on Christmas eve and with my shrimp I have a good, high, constant source of ammonia and am starting to see some results. As of yesterdays results my Ph has stayed at a constant 8, my ammonia is at 8ppm, nitrite is at 5ppm and nitrate is at 7ppm.
There is a sticky on this site that details everything you will need to know about getting your tank to cycle. Best of luck
Here are my Betta homes. I also have a 125 gallon African Cichlid Tank, a 10 gallon fry/hospital/quarantine tank. And a 20 gallon Console TV.
All of those tanks have WAY TOO MUCH water in them, you need to remove a few inches. It looks like your fish might be able to easily jump out of the fluval since it's not covered. Plus bettas need surface air to breathe, in those tanks they don't have any.
