3cmc questions

[luckylook.]

I have some question, if you can help me i will be thankful.
I use dcm for solvent.
My freebase cleaned first with water+sodium bicarbonate after x3 only cleaned water, smell is ok, but sometimes my freebase not clear. Can i use sodium chloride that will be more clear? Or what should i do?
Other... I make salting with hcl+cleaned water solution. If i check my ph then should check layers together or if separated should check different layers-layers or only layers together?
What temperature the best for salting? 0'C ??? I have professional cooler machine, i can control the temperaure exactly.
Thanks
