Nah i was Using Distilled with Silver,
But the thing is i have two rads one that i use and one that i don't use yet.
Im using a Thermochill PA120.3 the old version that i got from Someone on here,
I flushed it a couple times when i got it but i didn't give it too much thought...
After a while i noticed Stains in my Res and thus i come to find out i have the Dirtiest Rad on the Eastern Seaboard...
Im flushing it right now with just hot boiling tap water, but im headed to the store to get some 3 gallons of Distilled and such.
PS. the other rad is a 480 Feser, that i have yet to Flush or use but its brand new so i don't know yet
