Do plants give off oxygen in fish tanks?

Do aquatic plants add oxygen to water?

Do aquarium plants use oxygen at night?

Aquatic plants produce oxygen during the day, but use it up overnight. The remaining creatures like bacteria, fish and invertebrates need oxygen 24/7, so an enrichment with oxygen at night is definitely a good idea here.
