Hey Reefers,
First time running a herbie and I've been trying to dial in my siphon drain before setting the tank up for real. I've noticed that the water level in the return chamber fluctuates opposite the water level in the overflow. I realize that it will be more stable once I get it close to perfect but since the water level in the overflow needs periodic adjustments anyway, won't that instability mess with my ATO and therefore salinity?
I can get it pretty stable if I let i dial it in so there is a small trickle down the emergency to compensate, but even then I noticed a small change over the course of today. The trickle grows and the return chamber drops slightly.
Before i set this up i always thought that the return section stayed constant and I only had to tune the siphon to adjust the height of the water in the overflow?
Am I missing something?
Thanks!
