Video: What Diseases Do Aquatic Plants Suffer From?
Diseases of aquatic plants are usually associated with aging water, soil decay, improper lighting, deep planting, temperature inconsistencies, hydrochemical discomfort and exposure to toxic substances.
The main thing in the prevention of diseases of aquatic plants is optimal maintenance conditions, hygiene and careful daily care. When making a diagnosis, it is necessary to check whether the damage to the plant is caused by snails or fish, since the symptoms are similar in some cases.
Some signs and causes of diseases:
- Stopping plant growth - a lack of carbon is possible, which is often associated with too high a pH value for a given plant species.
- Sore and black roots - very fine, highly compacted soil.
- The plant quickly loses leaves on which small areas die off - lack of phosphorus.
- Too long internodes, rapidly developing thin stems, loss of leaves in the lower part of the plant, pale color of the leaf blade - low light.
- Too long internodes and small leaves - not the correct ratio between temperature and light (the higher the temperature, the stronger light is required).
- Too elongated tops of plants - a very powerful red part of the lamp spectrum.
- Withering and withering plants or partial damage to the leaf blades (holes, frayed edges, discoloration) are often the result of a change in the chemical composition of the water or a lack of any nutrient.
- Pronounced damage to leaf blades, especially in young plants with a shortened stem and a well-developed root system - stagnation of water in the soil is possible due to its high density.
- The leaf blades are covered with lime - lack of carbon dioxide.
- The leaf blades are very small - lack of power or too strong lighting.
- Leaf blades are yellow, older leaves turn yellow first and sometimes turn reddish - lack of nitrogen.
- Yellow spots appear on the leaves and they wither along the edges - a lack of potassium.
- Young leaves have yellow edges - lack of calcium.
- Leaves turn yellow, young at first, reddish color may appear - lack of sulfur.
- Yellow spots appear between the veins of the leaf, then these places die off, leaving holes behind - a lack of magnesium.
- The leaves turn yellow, the plant becomes glassy and dies - lack of iron.
- Leaf tissues turn yellow, veins remain green - lack of manganese (often caused by excess iron).
- In Cryptocoryne, the leaf blade, starting from the top, becomes vitreous, holes are formed and then it completely decomposes together with the petiole - "cryptocoryne disease".

The cause of this disease has not yet been established. It has been noticed that it often occurs as a result of a sharp change in the conditions of detention: a change in a large amount of water of a different chemical composition, a change in lighting conditions, replacement of daylight with artificial light and vice versa, a change in filter material, etc.
If the leaves begin to decompose, they need to be cut off, the plant residues should be sucked off with a hose, and the water in the aquarium should be changed to fresh water to save the root system. Cryptocorynes recover for a long time after an illness and, as a rule, do not reach their previous size.
Illness rarely occurs in an aquarium that has regular water changes and a normal amount of fish and plants.
