Introducing the Acrylic Isolation Box, a versatile solution designed to meet the diverse requirements of both freshwater and saltwater environments, as well as hobbyists and professionals alike. Available in a wide range of colors, this box measures approximately 3.5" square, excluding the suction cup or magnet. With the addition of the suction cup or magnet, the total length extends to approximately 4 inches. This Acrylic Isolation Box is an ideal choice for housing delicate organisms such as anemones and corals, particularly mushrooms that require containment. It also serves as a safe haven for sick or injured small fish, as well as baby fish with a body girth under 4mm. The box features a convenient hinged lid, allowing for easy access and maintenance. Its well-designed hole size ensures unhindered water flow, while its exceptional transparency allows for optimal light transmission. Arriving fully assembled, this product offers a hassle-free experience. For models equipped with a suction cup, simply attach the included suction cup by screwing it on. Alternatively, for models with a magnet, carefully slide the two magnets apart sideways and reattach them in your desired location. This plug and play design is suitable for both reefers and general aquarists. The suction cup design ensures effortless mounting with a thumb screw pressure suction cup. Boasting a superior hold, this specially designed suction cup surpasses the strength of most magnets, providing reliable support and preventing detachment or falling off the glass. Moreover, it eliminates any limitations imposed by glass thickness requirements. For those who prefer magnets, we offer a magnetic option as well. Our reef-safe magnets are exceptionally strong, crafted from the finest N52 neodymium magnets and fully encased in acrylic for waterproofing. Rest assured in your purchase, as our products come with a 1-year warranty from the date of purchase. Experience the convenience and reliability of the Acrylic Isolation Box, a must-have for any aquarist or hobbyist seeking a versatile and durable solution.
