So 50 nitrate needs to hold at 5-10ppm and phosphate at 0.05-.1ppm in new tanks with no coral load. Your water changes should put you at least close. I would think your phosphate is on the higher end so check level and use a GFO if it’s high.
You could put some macro algae in a box, but I suspect it won’t do much, needs to be sizable to work well.
2 liters in a 50g, yup, that’s a lot. Maybe cloudy your water.
If so, do a WC.
You’ll need to keep a close eye on Salinity,Alk, MG, Nitrate, and Phosphate, they must stay pinned, or if their are moving consistently in one direction, fix them.
If you can get Mexican or Astrea snails maybe 5 each, or 10 total. Put them on the rocks where the algae is, keeping moving them back to most affected areas.
What’s lighting this tank?
Number of lights and wattage…
