I use a SilverPuppy and make a gallon at a time in a glass jar. Use nite-lite heater, and it works good on the gallon size. I normally make perfectly clear CS with no detectable tyndall. PWT 9-12. I made two identical batches. One with Crystal Springs Distilled water PWT .05 ,and the other with Winn-Dixie brand dw PWT 1.5. The .05 was clear and the dw with the PWT 1.5 turned out "straw" color (light yellow) That was the only difference. Now I know why mine is yellow anyway.
