	note = {This study was conducted to evaluate the phytoremediation performance of acclimatized floating macrophytes on manganese contaminated lagoon in Brgy. Anonang, Cordon, Isabela from March to July 2022. Based on initial testing, it has been confirmed that the water of the lagoon is contaminated with high level of Manganese averaging to 0.6 mg/L. Acclimatization of floating macrophytes was performed for 14 days. The plants were acclimatized with different treatments, water hyacinth acclimatized in the mixture of carrageenan extract and tap water (T1), water hyacinth acclimatized in pure tap water (T2), water lettuce acclimatized in pure tap water (13), and water lettuce acclimatized with mixture of carrageenan extract and tap water (T4). After the acclimatization period, the experiment on actual phytoremediation was set-up in the shallow part of Anonang lagoon for 9 days.

The result showed that water hyacinth and water lettuce acclimatized within 14 days with both kind of bio stimulant are excellent in removing 100% of total Manganese in just three days of phytoremediation. The manganese uptake of both aquatic plants with bio stimulant shows no significant different with each other. All treatments evaluated in this study were all excellent accumulator of manganese on their body parts. In terms of metal uptake, RGR and BCF value, TI yielded the highest metal uptake of 115.96 mg/kg. RGR of 0.114 g/g day and BCF of 193.26 mg/kg/mg/L. The water hyacinth acclimatized with mixture of carrageenan extract and tap water (TI) is the most favorable interaction to be recommended for 3-day phytoremediation of Manganese contaminated water but all the treatments evaluated in this study can be used as they all excelled in manganese removal efficiency. Carrageenan extract can be used as bio stimulant for increasing the relative growth rate of plants to be used on phytoremediation but economically, pure tap water can also be used for acclimatization of plants as they both inhibited excellence in manganese removal efficiency.
