You could use a bit more calcium. I'd increase it to at least 250. Also let the pH creep-up into the mid to upper 7s since I suspect your water is still chilly. Add another 10-20 ppm of stabilizer as well to ensure your CYA is at least 30 or even 40. That should get you going. The important reference links are below in my signature. Have a nice evening.
