Purple primer?

[reefjunkie3]

The purple primer that one would use on pvc pipe...is that safe to use? Or should you just skip using the primer? I was worried that it might have some harmful stuff in it that could harm the tank.
Thank you.:bum:

its ok, FWIW you can get a nice clear primer than isnt so ugly:)

Thank you very much.......:D

Actually hardly ever use the primer. If the fittings are clean (new) you can wet both the male and female parts to be joined with the cement. give it a twist as you insert and you will have no problems

If anyone does use the purple primer, be very carful not to drip it on the linolium floor in your apartment...because that would be a VERY VERY bad mistake. :D

Think of it as faux coralline algae!

There's no need for primer unless your pump will exceed 140 psi in the lines. Save your money. Just my 2 cents.

If the white pvc pipe is going into the show tank, you can do what i did. First sand the whole lenth of the pipe to remove the 'glassey' shine and to provide a rough surface for coraline and other things to adhiere. Then paint the whole lenth of the pipe purple to help hide it until stuff starts growing.;)

The purple primer 'soften's the pipe for a few minutes while you apply the actual cement. It really isn't all that necessary, but if it gives you a bit more security, then go ahead and do it. I end up priming about 90% of my PVC connections, but will occasionally miss a few. ..

Thanks for the advice......I was told that the stuff would leech into the tank and kill everything......just glad that's not gonna happen!!!:D I like the sanding idea...think I will go that route....thank you all!!!!

Quick note; It won't leach (and kill everything) after it's cured, BUT, if you feel safer not using it that's fine as long as you keep the water preasure low (under140psi).
Whatever you do, keep in mind the smell test! "If you can smell it, don't put it in the water!" Do all the glue joints and then let it air out until the smwll is gone.

It won't leach into the tank any more/less than the cement will. Basically, it cures with the cement (actually faster), and once cured, its pretty much inert.
