Question to anyone who has made/used a gunge tank: What diameter aperture did you use for the hole? I have a 50 Litre tank, intend to use thick but still flowing gunge (slightly thicker than custard, sticky, less 'umbrella effect') and want it to flow fast but not dump it all out in a couple of seconds.
Not looking for exact dimensions, just any tips and warnings from people who have done this before.
Love you, too
