However, there are a few drawbacks to consider. While the included Tetra Whisper PF 30 Power Filter is known for its quiet operation, some users might find it not the most powerful option for maintaining optimal water quality, especially if they plan to keep a high number of fish. Additionally, the 200-watt heater should keep the water at a stable temperature, but it might require periodic adjustments depending on the room temperature and the specific needs of your fish.
