or just read it here and miss out on the closeup pics
:
I learned that the black coating is possibly a good thing, The coating blocks corrosion. However i think that this coating only forms on Aluminum.. so are additives worth while to put in a copper and brass system? also i would think that the coating may reduce the performance of aluminum.... now for the update: everything has gotten darker, The PurpleIce more than the Redline (with new info this would indicate that purple ice is better at stopping the corrosion)... the Distilled water STILL has no signs of corrosion. With the purpleice it seems that there is pitting where the bubbles stay...Now, i would figure that in a functioning system with moving water, that the bubbles would not have a chance to stick to the aluminum... So.. you know what that means... another test, this time with pumps.
this may also give some info to the people wanting to know if they should leave their pumps constantly on or not!
