Additional equipment with useful features allows you to improve the care of heat-loving fish, to avoid their death.
Manufacturers offer waterproof fixtures that differ in power, type of installation in the aquarium (internal or external). Experts recommend purchasing modern electrical devices at the rate of 1 W per 1 liter of water. When choosing a device, in addition to the volume of the container, one should take into account the thermal conductivity of the material from which it is made, its configuration, the presence of a lid, the temperature in the room, etc. Our mini-rating contains the most popular models among users that received the highest marks for technical potential and operational reliability.
