I wouldnt trust stability to create an instant cycle or neutralize everything, but I dont really know what you are trying to accomplish...so with that being said, use as little chemicals as possible. I would just stick with prime.
Ok. Now the picture's in focus. Don't panic, mistakes are why they put erasers on pencils. Save your money on the Stability. Monitor your parameters, do daily W/C's using Prime (or my choice, AmQuel+). If you can score some media from an existing tank, that might speed things along. JMPO, "T"
