1. Ecological tanks need to be well matched, and aquatic plants, organisms and nitrifying bacteria should reach a balance point. In the simplest ecological tank, only aquatic plants and tool shrimp can be considered, because tool shrimp eat algae, but not food. Algae grow naturally, shrimp control algae, and daily maintenance is to add water and liquid fertilizer;
2. If you are a novice, choose a better aquatic sediment. Recommended: Wuwei Mud, Ada Mud. A good grass-mud horse can get twice the result with half the effort and build up confidence. Choose aquatic plants as entry-level aquatic plants;
3. The density of aquatic plants is about 50% to 75%, which is easy to control algae and can provide enough shelter for small fish and shrimp.
