The window leaf is more popular than ever to create a revitalizing jungle atmosphere in living rooms and offices. Less well known is a hidden talent that clever monstera-loving aquarists know how to capitalize on. Read here what aerial roots have to do with clean water and happy fish.
The roots of Monstera and other plants provide a retreat for fish
Aerial roots as a water filter, spawning ground and retreat - this is how it works
The Monstera sends out its aerial roots to collect water and nutrients. In particular, the need for nitrate is pronounced, because this nutrient makes an important contribution to the growth of the mighty leaves. In the water of the aquarium, however, nitrate is undesirable because it is unhealthy to toxic for many fish. Read here how to reconcile these two characteristics:
- Place the window leaf in close proximity to the aquarium
- Attach a cross brace to large aquariums as a flower bench for the window leaf
- Lead as many of the aerial roots into the water as possible
- Use climbing aids to keep the leafy shoots away from the water
In this modified form of hydroponics, a dense network of fine roots develops. These filter the nitrate out of the water so that it can be used as nitrogen. The roots are very welcome to the fish in the aquarium as spawning grounds and hiding places. As practice has shown, the nitrate content in the water fell from 60 mg per liter to 5 mg per liter within 2 months. 12 aerial roots climbed into the water from a 3 m high plant.
Modify water supply
The more aerial roots reach into aquarium water, the less often you will water the window leaf. The nitrate filtered out of the water, on the other hand, does not come close to covering the high nutrient requirements of a powerful Monstera. Therefore, please continue the usual fertilizer intervals as usual.
tips
Anyone who limits the window leaf to its decorative value and its function as a water filter has not yet tasted its fruit. Where a Monstera deliciosa feels at home, sooner or later it will bloom and bear fruit. These are up to 20 cm long and have green plates as shells. When fully ripe, the skin peels away to reveal a creamy-white flesh with the texture of banana and the flavor of pineapple.
