i remember that thread, SHD did a great job explaining it.
I somewhat differ in option over the glueing part- making a completely sealed unit, & the venting hose. Venting hoses are solutions of the past (no offence SHD - you old school trojant

) To give an example guys- When i was building my nano (only cause its fresh in the mind & not beer4gotten) out of that new age funky irragation materials, because its made to be completely sealed, there was no choice but to find an air control piece.
But as soon as your using
PVC, the rules change - I prefer to whistle cradle my top cap & leave the stand pipe only assembled by hand. Think of the standpipe as a living breathing entity , the more restricted you make it, the more that can potentially go wrong. Plus it can potentially balance osmotic pressures far better from multiple sources rather than starving or fighting for it at our pre determined locations. Does this make any sence?
