Submerged Oxygenating Pond Plants consume lots of nutrients and release oxygen during the daytime. Note in hot summer months these plants also reverse the process at night so for ponds with a high fish load you do need a pump. Only Hornwort and Vallisneria are recommended for colder climates. Anacharis Densa is fairly cold tolerant but now illegal in many states. Cabomba and Anacharis Najas are not cold hardy.
