Factors To Consider When Selecting Philodendrons For Aquariums

Philodendrons are a popular choice for aquarium enthusiasts because of their attractive foliage and low maintenance requirements. However, not all species are suitable for a water-based environment. If you are considering adding a philodendron to your aquarium, there are several factors you need to keep in mind.

Below are the key factors you should consider when selecting philodendrons for your aquarium.

Lighting Requirements

Water Temperature

Philodendrons are native to tropical regions and can thrive in a warm water environment. The ideal water temperature for most philodendrons is between 72°f and 82°f. Therefore, make sure the temperature in your aquarium is within this range before adding a plant.

Ph Levels

Philodendrons thrive in slightly acidic to neutral water with a ph range of 5. 5-7. 0. If the water in your aquarium is too acidic or alkaline, it can negatively affect the plant’s growth.
