Narrative:

We were cleared for the visual approach to runway 26 in jax. We descended to 1600 to intercept the FAF (final approach fix). About 2 miles out from the FAF; we got a G/south* (glideslope). I followed the glideslope; and just around 1000 ft we got the altitude warning from ATC. I corrected my descent and continued to a visual approach with the VASI (visual approach slope indicator). I believe we received an erroneous glideslope indication. I was fixated on the glideslope and although I had visual contact with the runway; I couldn't tell we were low until we were coming straight in.
