Potential problems with Toadstool frag?

[Probiesmasher]

I've noticed my toadstool frag has been bending to the right pretty substantially these past 2 weeks or so, not sure if its just doing its thing or I'm doing something wrong. The stalk looks a little iffy on the bottom half, so might be dying? Its in about the middle of the tank, pretty decent flow and light from what I can tell. Admittedly, I have been lacking on weekly water changes the past few months, but have been keeping up with them the past couple weeks @~15% a week. Thoughts?

Edit: Also forgot to mention I have recently switched salts, from Instant Ocean reef crystals to Red Sea Coral Pro, mixing them for a few waterchanges to kind of help the transition.

Tested as of today:

Salinity: 37.3

Amonnia: 0

PH: 8.38

Nitrate: 0ppm

Nitrate: ~30ppm

Calcium: 580ppm

Phosphate: 2ppm

Alk: 9.02

Looks fine. I'd get your salt down to 35ppt though.
