When adding plants, it makes a significant impact when you have enough plants to immediately cover at least 70% of the tank substrate.
When adding plants, it makes a significant impact when you have enough plants to immediately cover at least 70% of the tank substrate. A well planted tank is the best defense against algae. Plants have a very significant impact on the micro-climate of planted tanks. When plant mass is dominant and healthy, the tank becomes very algae resistant, even in the presence of higher light and nutrient levels. As plant growth improves and plant density increases, it is almost always paired with a decline in algae.
