dc.description.abstractIn the experiment, <em>Caulerpa lentillifera</em>, <em>Caulerpa sertularioides</em>, <em>Caulerpa serrulata</em>, <em>Halymenia microcarpa</em> and <em>Chaetomorpha valida</em> were employed. The seawater utilized was high in phosphate and nitrogen, and the macroalgae were cultured for 72 hours. We assessed the capacity of five different species of macroalgae to remove nitrogen and phosphorus from seawater by examining changes in the concentrations of ammonia nitrogen, nitrate nitrogen and active phosphorus. The results of the experiment demonstrated that five different types of macroalgae had noticeable removal effects on nitrogen and phosphorus. <em>Caulerpa sertularioides</em> had the best removal effect on ammonia nitrogen, with an absorption efficiency of 96.4%. <em>Caulerpa lentillifera</em> and <em>Caulerpa serrulata</em> had the best removal efficiency of nitrate nitrogen, with an absorption efficiency of 95.5%. <em>Chaetomorpha valida</em> had the best removal effect on active phosphorus, with an absorption efficiency of 78.4%.
