Prodibio Question--Need To Know ASAP

[MMAX]

I sent a PM to Aqua-Digital about this but he hasn't replied yet. Maybe he's gone for the weekend. Need to know right away because I'm due for dosing tomorrow. I've been using Prodibio since the beginning of May, I've dosed for 6 weeks and have not used reef builder yet. I mail ordered another kit but due to the damn strike, it sat at the post office for a month. So, 2 weeks ago I missed a dose. Tomorrow, should I try adding the reef builder or wait another 2 weeks before using it? Also do you shut off your skimmer 4 hours after using it?
