How many fish do you have now and what size? The skimmer’s job is to remove dissolved organics from the water and while dissolved organics definitely do contribute to elevated No3 levels, Po4 is not really removed by a skimmer but high PO4 and high No3 is usually a sign of over feeding, not sufficient water changes or detritus building up in the system such as in the sand bed due to a lack of vacuuming the sand bed. With an 650l system, you’d need a very heavy fish load to keep that skimmer consistent and producing well. If you have the pump speed running between 28 and 32w and want to see more in your collection cup, then close the wedge pipe some to make the skimmer skim more wet.
