I am busy setting up my tank and the Pvc joints aint water tight. What is the best thing to use to bind them. Marine silicone, super glue or i saw Bostic Pvc cement or something. Is it reef safe? What do u guys suggest? Thanks in advance.

if its screw fittings, just use thread tape, if its the push(glue) fittings then use PVC cement or equivilent, just let 24hrs to cure.

PVC glue. Literally melts the 2 surfaces together. Impossible to redo. So make sure you do a good job first time round.

Yip PVC weld is the thing.

Tangit, Bostick or any of the others will be fine

For temporary pipe connections, silicone should do it. Then you should be able to take it apart and re-use the connections for next project. Just let it cure and dry properly.

Use PVC weld glue, as mentioned above. Before you apply the glue, make sure that both pieces to be welded are perfectly clean - use a paper towel soaked in acetone to do so.

Also keep in mind that you will have perhaps 5 seconds before the glue sets, so once you've pushed a pipe into a fitting then that's it, no chance for correcting any mistakes...

Good luck - it's easy if you've done the planning... Oh, and remember, measure twice, glue once :)

A Beautiful place!
Definitely pvc weld/glue. What I do is take sandpaper and make both ends to be joined a little rough. Apply the glue evenly in the circumferrence. Turn the pipe/fittings as you join to get all air out and spread glue everywhere. Wipe access glue. Like Hennie said, make sure about sizes as it sets quickly.
