PEX for mouning frags. Will it leach?

[JCOLE]

Since PEX has not been extensively used in marine systems, it may be best to avoid due to the unknowns. CPVC or PVC may be safer options. Although, they are known to leach some Sn. However, I have not seen any elevated Sn in ICP analyses after installing new PVC.

I would go with gray PVC since it will be less of an eye sore than white or bright colors. They also make PVC in clear ($$).

I agree. I think I am going to just use the Acrylic like I originally planned. I will mount the top of a frag plug to the acrylic and wait to dry. Then mount to the rockwork. This will allow me to mount a coral or top of frag plug to the rod easily. Going between this and the CPVC route due to the size.

I went ahead made up some of the acrylic mounts last night. I posted what I did on my build thread if anyone is interested.
