Ok this is probably a really silly question but don't your carto tanks leak when you lay them down? The one I have does![]()
I've got all kinds of carto tanks--Phiniac, IBTanked, X8, generic smoktek, and an AMP tank (which is technically an Atty Tank, not a carto tank) and none of them leak if I lay them down.
One of the secrets to sealing up your carto tanks is to be sure the o-rings (around the caps, AND inside, around your carto) are lubed up before assembly. Putting together a carto tank with dry o-rings makes it more difficult to get together, the friction can damage the o-rings over times, and a little liquid on the rings just helps them seal up better.
I use a tiny bit of straight VG on my finger, which I wipe on the o-rings, AND on the inside of the tank tube, and the outside of my cartos before assembly. This makes them go together VERY easily, and they seal up like a champ...
