My Ca Reactor has been around for 5 years and the LFS is using one of my first skimmers built 7 years ago. I know it's not as clear, but it's always stayed crack free and not leaked. Just wondering if your experiences have been different?

What I see a lot is crazing if extra care isn't used. For example glueing joints that have induced stresses from bending or polishing. Also glueing parts that are not at room temp. They say this can be avoided by anealing the parts but who's wife will let you cook plastic in the oven. I was caught, once was enough.

I wouldn't have even tried, I got enough crap for baking rocks and stuff after bleaching.

I never got much crazing, but all my joints were just plain old straight edges. I wonder if different suppliers have different grades? I got my tubing at a local shop, not IPP

There is a lot of really informative but dry reading in the tech support area at one of the acrylic manufacturers site (Cyro) for info on this subject. One would need to create a user name to get at it.
