3. Detailed operation guide
1. Key points for using UV germicidal lamps
• Choose the UV lamp power suitable for the size of the fish tank (8-10W per 100 liters of water)
• No more than 8 hours of continuous use per day
• Be careful to avoid fish and beneficial bacteria
2. Scientific water change process
• Do not change more than 1/3 of the water for the first time
• Change 1/5 of the water volume every 2 days thereafter
• Use trapped water and control the temperature difference within ±1℃
3. Recommended species for biological control methods
| biological species | Algae removal effect | Applicable environment |
|---|---|---|
| scavenger fish | ★★★ | Medium and large fish tanks |
| black shell shrimp | ★★★★ | Grass tank/small tank |
| Apple snail | ★★★☆ | Various fresh water tanks |
