This would mean those plants would store CO2 at night and use the stored CO2

According to Diana Walstad some water plants convert CO2 at night into
malate, which is used during the day to generate CO2 for photosynthesis.
She also says this strategy is not as common in aquatic plants as it is in
terrestrial ones. ("The Ecology of the Planted Aquarium" pp. 96-97)
