I just bought a some 1/2 '' pvc
pipe and several varying fittings from home depot to make a frame for my live rock so I can get the look i'm going for. The problem is that the pvc
pipe is rather dirty... I am going to rinse and scrub it with tap water and avoid using soaps but is there anything else I can do? Is there a chance that I could polute my water by any unknown residuals on the framework? Is this typical?
