I'm setting up an old iron 30 inch stand that's ~4inch from the floor to the bottom shelf. The other I have is on 8 inch cinder block & syphoning is ok, not great but the substrate is very fine (Flourite sand).
I'm a bit concerned about top-heaviness & instability if I boost it much higher than 8 in or so for stacked tanks 10 or 20g on the bottom & 20 or 29 on top.
How high is safe but easier to syphon?
