does adding a biocide, such as pt nuke, cause any ill affects? i have some already and was thinking of adding a drop to my water/killcoil just as a safe measure. seems like it wouldn't hurt anything...
There would be literally no point. The silver ions that break off the coil is PLENTY enough for the amount of water in a loop. Some people have found it leaves a clear film on the inside of tubes/blocks, but I don't have any input of my own as I've never used PT Nuke.
