    Painting PVC, Reefsafe?

    I've been doing some searches on the 'net to see whether painting PVC is reefsafe.

    I basically want to paint some PVC that will be submersed in the tank BLACK. I've read of several ways of doing this, one thread on RC even mentioned using a Big black SHARPIE marker...

    Has anyone done it? What product did you use? How is it holding up over time?

    THanks!

    I read on another thread about using one of those "Mega-size" permanent black markers to make white pvc black. If I remember correctly, it was a thread started by Lunchbucket, and he had asked Randy Holmes-Farley about potential problems with doing this, and Randy gave it the thumbs up.

    So, I will be buying new pvc fittings to color them with a Giant sharpie

    Here's some other references that I've found regarding painting PVC...

    I painted all my pvc inside my tank using black epoxy paint from HD.
    Two part black epoxy paint. There are some that are reef safe. I used some for my pvc rock stand that I used in the tank.
    I used Rustoleum appliance black for over half a year without any problems.

    You can use krylon spray paint. Thats what I did for my stand pipes in my 110. Never had a problem in over 3 years.

    Tang-Man, Stewart brought home large heat shrink tubing to cover our white PVC. I didn't get it done before we put the closed loop in the tank, but want to do it when we redo everything.

    I'll remember that. He was able to pick a couple of short lengths up from the garbage. Now I have to use it!

    Vince, I had painted a bunch of pipes with flat black Krylon spray paint awhile ago and there was no problems with it. The trick is to let it dry thoroughly and preferably let it stay out of the water a few days so that any gases that are residual from the paint drying have a chance to dissipate.
    Why pain it though? Why don't you just let it encrust with coralline or simply use the grey schedule pipe? I painted and worried about this in the beginning but now I don't bother because everything gets completely encrusted and hidden. Also, do as I've done and place some of the encrusting soft stuff such as buttons or star polyps on the pieces and let them cover them for a natural look.

    Krylon, huh?

    Did you prime or sand the pipe first? It didn't flake away over time?

    I wanna paint it because until it does encrust over, I don't want to look at ugly 1.5" white PVC intake pipes along the back wall of the tank.

    Know what, I wouldn't bother and I wouldn't chance it. what happens if the stuff starts peeling, it'll look like crap. you could use grey or why don't you use black ABS??? iTS ALREADY BLACK. why trouble yourself with painting PVC when ABS is totaly safe. You could also use white PVC as it will get covered FAST! with corraline algea.

    Cool

    ABS is totally safe to use and a hell of a lot easier to find fittings for.
