The first lesson here, Grasshopper, is that in this hobby "Nothing good happens fast". Nothing you can do to "speed up the cycle" will benefit your tank, nor your future livestock, in any way. You're best off to keep the lights on a short cycle and let things run its course. If you've been cycling for some time and the diatoms are currently in bloom then chances are you're near the end of your cycle. If your numbers are good I'd add a good sized clean up crew and begin considering what your first fish would be.
