Macroalgae clogging

[Atxmedic]

Trying to get the Fuge started. Having an issue with Macroalgae clogging the flow to the skimmer section of my sump, almost like there is a suction being created by the lower water level in the skimmer section. This is causing the water level to drop in the return section and kick the ato on. This is a Waterbox sump. Any suggestions?
