With a finely constructed base, you don’t need to worry about the lighthouse floating around once you place it underwater. Super simple to clean: before placing it into your tank, or as you perform regular cleaning and maintenance, simply wipe down and rinse off the ornament with warm water. Never use soap, as the residual soap particles can harm your fish. Please note: Your fish might use the top small entryways as a swim-through. Nautical décor: the sand & seashell lighthouse also makes for a great decoration piece for parties, weddings, beach houses, nautical-themed rooms, or the bedroom of an ocean-loving child who’s into all things aquatic.

This heater easily maintains healthy water temperature within a 1° accuracy, and can be set anywhere between 68 ℉ and 89 ℉, by using the red control knob. Our Cascade Aquarium Heaters are factory set to 76 ℉, and are safe for either freshwater or saltwater fish tanks. The 150W model works great for 20 – 30 gallon tanks. Visible & Accurate Temperature Scale: With an easy to read setting scale in both Celsius and Fahrenheit, it’s easy to see the temperature adjustments being made. To increase the temperature, rotate the control knob counter-clockwise, and to decrease, rotate it clockwise; or, follow the + and – symbols located near the control knob. Orange Pilot Light: Our Cascade Heat Aquarium Heaters feature a pilot light that indicates the heating cycle status. This means that it will go on and off by itself as the thermostat cycles the heating element on and off. In other words, orange light = heater is on. Similarly, these aquarium heaters make a faint click when turning off. Additional Features: In addition to being composed of heavy-duty and shock-resistant glass, these fully submersible aquarium heaters can be placed either horizontally or vertically. There’s also a built-in minimum water level indicator at the top, colored in red. Please Note: Do not operate heater outside of aquarium, and never submerse a hot heater into an aquarium – only submerse a cool heater. After placing the heater into your aquarium, wait 15 minutes before turning on. This allows the thermostat to adjust itself to water temperature. Measurements: Overall Length = 11” / Overall Diameter = 1.1” / Suction Cup Diameter = 1.25” / Wattage = 150W / Voltage = 110V.

Cascade presents bio-floss replacement poly fiber floss pads for cascade 500 canister aquarium filters. This 6-pack of cascade bio-floss poly fiber floss pads is specially designed for cascade 500 canister filters, allowing for simple and easy media replenishment. Don’t worry about cutting to size, these pads fit directly into media trays within the cascade 500. Great for freshwater and saltwater aquariums. Essential mechanical filtration: bio-floss helps clear up discolorations and reduce foul odors by physically trapping tiny particles of detritus, such as fish waste, uneaten food, or even decayed aquarium plant materials. This assists with establishing and maintaining healthy, crystal-clear water within your tank. Beneficially convenient: along with being a vehicle for mechanical filtration, bio-floss also promotes the colonization of beneficial filtration. This in return, helps regulate ammonia, nitrite, nitrate, and phosphate levels. Proficient & prolonging: Our poly fiber floss pads help prevent the clogging of finer filter media, allowing them to perform better at their own tasks, which improves overall filtration. On the other hand, bio-floss extends the lifespan of other media and the filter itself.
