I'm no botanist, aquahorticulturist or anything close, but I think philodendrons (fast growers) will sap nutrients/nitrogenous waste rapidly from water. That means for all those who love playing chemist with iron, fertilizers, etc. will have to compensate for this nutrient drain. For my tanks and my anubias, java moss and occasional bolbitis (the only plants I ever hope to grow)- no worries, all have thrived despite the terrestrial plants. - - Steve Waldron
