What is the sg of the tank now? If its low end brackish, 1.004 or lower, than the mollies should have no problem acclimating too it. Drip acclimate them like you would any new fish and you shouldn't have any problems.
ok so i took the GSP's back and put in an order for some figure 8's...since the GSP and figure 8's are the same price basically ive prepaid for the figure's with the refund from my GSPs
here are a couple pictures the first one is with the decorations i got so far...i have since got a new bulb and wanna get some plants when i get the plants ill take more pictures with the mollys and bubble wands running
here are the GSP's i originally bought and took back to the LFS
