Well I just took the plunge and rebuilt my system with a AquaCoil Rad and used my home made Highlighter UV dye and WOW, nice bright green and all is good Now.
I put an extra mag drive shaft into solution for testing and it did not bother it, also some copper pennies. test went well for a week. Now Im using it in system.
