The algae in the display will get all the phosphate/nitrate it needs before the water goes into the sump and cycles slowly through the GFO or bio pellets.
2. Try dosing Hydrogen Peroxide. Take a 2ml syringe and draw up 0.3ml of 3% Hydrogen Peroxide(H2O2) then draw up another 1.7ml of RO/DI water. Add this into the air inlet of the skimmer. Observe the tank the rest of the day. If no signs of stress of any inhabitants, closely watch any shrimp, then try procedure again that evening. If everything is good the next morning repeat this for a week and see if there is a difference in the algae. If no difference after a week increase dosage to 0.5ml H2O2 and 1.5ml RO/DI water. Most of the Hydrogen Peroxide will react in the skimmer. UV sterilizers have a tendency to neutralize residual ozone and H2O2. If you observe any negative reactions in any of your animals you can add a chlorine neutralizer to get rid of the residual H2O2 immediately.
Cheers,

Hi Tim
I am using Foz-down in the auto top off storage water container ATM, How much should I use in the display tank and how often? My tank is a RSM 250/66gallon.
