I have always used swing arms even when I worked in the hobby. The Fluval Evo 13.5 was the first tank that caused me to purchase a Refractometer. The evap is low on this tank but the way the weir functions along with the main display. The skimmer made it a whole lot more fun it’s difficult to know how much evap your getting. Well more than I thought I had a target salinity of 1.025. The refractometer calibrated showed 1.027. Easy to fix small tank a few points.
I know the debate will go on. But that just made a believer out of me. I’ll be using the refractometer from now on.
