when i installed my tank i made sure it was 100% level. I was having a problem with the water test on one side and now i know its because the left side weir is slightly higher than the right side. Therefore i get more flow on the right side (dual overflows). How do you adjust the slots in the weir to be equal with the other side? any recommendations, maybe cutting into the weir a bit to allow for same side flow??
thanks
