Ok I think I understand what a skimmer does. My question is wouldn't it be most beneficial to have the skimmer hanging off of the Main tank verses inside a sump? I just figure there would be more waste to be collected from the surface of the main tank verses the sump considering there is more surface area. Then if you have an overflow and sump the main tank would always be at the same water level so the skimmer could be set for optimum performance where as in a sump you always have to worry about water levels in the sump dropping due to evaporation. Also keeping the skimmer on the main tank gives more space inside the sump to be used as a refugium to improve water quality even more. The only downside I see to hanging the skimmer on the main tank is it is not pretty. I guess the purpose of a sump is to move equipment to the bottom of the display to not be seen and I see the point however I am thinking a refugium instead of a sump is the way to go for me. Just curious if anyone had input on this topic.
