I have an SPS dominated 75 gallon tank, and I'm dosing 81 mL per day right now, and I thought that was a lot. I would test for Mag, if your Mag is low it could cause the elements to precipitate out.
Furthermore, I can debunk the theory of "don't dose at the same time". I have been dosing for 2 years at the same time and not had any issues with precipitation. Just make sure you dose into an area that has adequate flow and at a slow enough rate for the elements to dissolve in the water before combining with each other.
