You don't enjoy being in water that's too cold or too hot for comfort, and neither do your fish. If the water in your tank is too cold, it leads to a slowed-down metabolism for your fish. This results in them becoming sluggish and sleepy. If the water in your tank is too warm, it leads to a fast metabolism. This results in fish being a little too lively and hyperactive. Tetra HT10 50 Watt Submersible Aquarium Heater has an electronic thermostat that automatically adapts to keep the water at a perfect temperature. It features an indicator light to let you know when it's running and heating the aquarium. The heater will also shut off automatically if there's an electrical short, ensuring everyone's safety.

At Marineland, we design our filter cartridges to meet the absolute highest standards of water purification, performance, and operational ease. Each pre-assembled cartridge slides easily into place, providing superior mechanical and chemical filtration, and making replacement fast, dry and effortless. The cartridge mechanically filters water through a pad of double thick poly-fiber. Debris and waste particles are trapped, and water is chemically filtered through Marineland's Black Diamond Premium Activated Carbon.
