? The oxygenation effect of aquatic plants is better. Water plants are divided into negative and positive, and the most obvious difference between them lies in their different needs for light. Negative aquatic plants can grow well without light, so they do not require high light, so they do not need frequent photosynthesis. However, the growth of positive aquatic plants will be greatly limited without light, because they like light, so they have strong photosynthesis ability, so they can release more oxygen.
are the positive aquatic plants? 1. Dwarf pearl: Dwarf pearl is a common positive aquatic plant, which originates from Australia and New Zealand and is suitable for planting as a prospect aquatic plant. In order to make it grow well, besides providing sufficient light, it should also receive a large amount of carbon dioxide, so that it can develop better.

This kind of aquatic plant is generally used as the middle or back scenery aquatic plant, which is suitable for survival in the environment of 15-24 ℃, and the requirement for pH is about 6-7. It should be noted that too high temperature will cause it to rot.
3. Palace grass: Palace grass, also known as Newton grass, is an annual aquatic plant distributed in tropical and subtropical regions.
