🌱 How to Care for Brazilian Waterweed to Prevent Slugs and Snails?

💧 How to Water

Egeria densa is not watered: it is an entirely submerged plant, so the concept of watering frequency does not apply. What matters is the quality of the water it lives in: keep it clean with regular partial water changes (10-20% every 1-2 weeks), avoid untreated chlorine and heavy metals, and pay attention to copper-based products (used against algae or parasites), to which this plant is very sensitive. Good water turnover and proper filtration are more important than any 'watering'.

☀️ Lighting

It prefers moderate to intense light, ideally 6-8 hours a day with dedicated aquarium lighting: the more light it receives, the more compact, robust, and bright green the stems will be. In low-light conditions, it tends to stretch excessively, with sparse leaves and dull color. It should be kept away from direct sunlight, especially in summer, to avoid overheating the water and algae proliferation.

🪴 Ideal Soil

It does not require a rich substrate: it adapts well to fine gravel or sand, where the roots anchor only for stability, or it can be left to float freely without rooting. It does not need mineral fertilizers in the substrate, as it feeds primarily through its leaves by absorbing nutrients dissolved in the water.
