How do you figure the low pH caused the ammonia problem? Chances are your
tank was just going through its cycle and your ammonia problem was caused
by excessive waste and an insufficiently developed nitrobacteria culture.
Most new tanks go through this cycle within the first two weeks of
introducing fish. I have seen a low pH caused by excessive nitrogenous
wastes (too much O2 being removed from the system, etc.) but never the
other way around.

OP's tank was set up in mid-December so it shouldn't be cycling. OP
didn't mention how low the pH crashed, but pH below 5.5 inhibits
nitrification and will lead to an ammonia problem. It's quite possible
to crash pH well below 6.0 with RO water.
