API® MELAFIX fish remedy is a completely natural antibacterial solution designed to address infections in fish. Common bacterial issues include open wounds and abrasions, tail rot, cloudy eyes, and mouth fungus. This remedy also aids in the regeneration of damaged fins and tissue. It can be applied when introducing new fish to an aquarium—especially to ease the transition from store to home—or if an infection is suspected but not yet confirmed. Some fish purchased from pet stores may already harbor diseases at the time of sale, which can be hard to identify in their initial stages. The API MELAFIX fish remedy is safe for your biological filter, will not change the pH levels, and will not discolor the water. Use 5 ml. for every 10 gallons of aquarium water. For treating diseases or wounds, administer daily for a week. After 7 days, perform a 25% water change. Continue treatment if needed. When introducing new fish, administer daily for 3 days.

Long ago, before engineer Eugen Jäger created the aquarium heater, there wasn't a satisfactory way to maintain the ideal water temperature. People utilized various complicated and sometimes odd methods, like placing the aquarium in sunlight or near a heater or stove.The EHEIM thermocontrol aquarium heater is an advanced version of the classic heating element, and the thermocontrol-e represents the latest electronically controlled model.Temperature can be accurately set between 20 to 32 °C, with a control precision of ± 0.5 °C.The temperature remains stable, and a control lamp indicates when the heater is in operation.This heater is completely waterproof, fully submersible, features dry run protection (Thermo Safety Control), and is suitable for both freshwater and saltwater environments. One of its most notable advancements is the glass coating:• It increases the heating surface,• compresses the heat, ensures optimal and consistent heat output, and• serves as a heat shield (the aquarium inhabitants can safely come into contact with it).The coating is made from specialized laboratory glass, designed for research purposes. Therefore, it is free from pollutants that could leach into the water. It is resistant to chemical and biological damage, with no cracks or hairline fractures to allow condensation to form. It is also impact-resistant and can withstand extreme temperature variations, such as those encountered during water changes.Diameter Ø:36 mmHeight:496 mmPower at 50 Hz:400 WattMax. temperature:32Sea water:YesMin. temperature:20 Freshwater:YesPackaging:6 Part (s)For aquariums up to approximately:1200 LitersFor aquariums of about:1000 LitersManufacturer warranty:3 Year(s)
