Sea lettuce working too well

[yellow tang lover]

Okay so a couple weeks ago I added some sea lettuce before I added it I couldn’t keep my nitrates below 30 and phosphate below 1 but the sea lettuce made my nitrates zero and phosphate 0.05 I know phosphate is good but how to I increase my nitrate because I have lps and soft corals and they need like at 2 nitrates I think but they are still doing good I dialed back my Fuge from 12 hours to 4 hours should I do anything else

You could trim the sea lettuce and remove some to lower the nitrate uptake, or add more nutrients by feeding more/heavier
