Hello all!
I just have a quick question... Regarding the IOS systems in tanks like ocean free nano space tanks and others out there, what's the water level like in all columns? As I seen in shops the water level at the pump column is lower but my tanks with IOS tend to have all equal water levels... And as I observed the design is seems that that would be the case but how come the water levels are different when I see them outside is there something im doing wrong?
Cheers!
