Tips for choosing aquarium lights

       The first step: Calculate the wattage of the water grass lamp required by the water plant tank

　　 In fact, there is a rough formula widely circulated in the aquatic world for the wattage demand of aquatic plants, which can calculate the theoretical value of demand. Remember, it is a theoretical value.

　　 Take the fluorescent tube (T5/T8) as an example (similar to other types of lamps):

　　 Shallow tank: For those with a water depth of 30cm (excluding bottom sand), the wattage of the grass lamp per liter of water is about 0.5～0.6W;

　　Medium tank: For those with a water depth of 30cm～40cm, the wattage of the grass lamp is about 0.7～0.8W per liter of water;

　　Deep tank: For those with a water depth of 40cm～50cm, each liter of water needs about 0.9～1.0W of water grass lamp wattage.

　　 Reminder: The green water plants are calculated at the low standard, and the red water plants are calculated at the high standard. The calculated result can be used as a reference value, but it is better to compare it with the actual condition of the aquarium. If all the plants in the aquarium are negative, the calculated value may be slightly higher than the actual situation. If the plants in the aquarium are all bright plants, the calculated value may be slightly lower than the actual demand. At this time, you must determine how much light you need based on the theoretical value and the actual situation of your water plant tank.

Step 2: Choose the type of lamp

　　We learned from the previous article that as long as the spectral peak of the lamp output matches the spectral range of chlorophyll a and b absorption; the light emitted by the lamp can satisfy the viewing needs and can be used as aquatic plants for aquaculture.

　　Through the introduction of various lamps, we have also learned the advantages and disadvantages of various lamps. As long as you choose the suitable aquatic lantern according to your own conditions and through comparison.
