Diagnostic of problems for aquatic plants
|Weakened, fragile and yellowed leaves.
Rotteness of the stem, weakened stem
|Lack of light||More light! Light exposure for 10 or 12 hours a day at appropriate intervals.|
|Gas bubbles appear at the base of the plant.
Weak root structure.
Black rotting of the stems.
|Problems in the sublayer||The base has to be weakened.
There is a large amount of organic substance with heavy decomposition on the surface.
|After a long time, the plants fall behinf in their development.
Too slow growth.
|Lack of oxygen||Check the lights, filters.
During the day provide more light and CO2 for the plants and more oxygen at night.
|Young leaves have a yellow color.
|Lack of potassium.||Add more potassium!|
|fragile and yellowed leaves.
Too little iron, too little potassium
or too harsh water.
|Ferric chloride||Add more iron!|

|Lack of nitrogen||More nitrate!|
|Disease of Cryptocoryne species:
The disease begins with small holes appeared on the leaves, then the plant goes rotten and the root goes rotten.
|Crypto rottennes||High level of nitrate.
The sharp drop in temperature, sudden environmental changes, frequently moving of plants from one place to another (transplantation)..
