Aquael Ultra Heater Day & Night 100W

The Aquael Ultra Heater Day & Night 100W is a smart electronic aquarium heater designed to replicate natural temperature fluctuations found in aquatic environments. Its advanced Day & Night mode automatically reduces the temperature slightly after lights-out, simulating a natural nighttime cooling cycle that supports fish metabolism, breeding behaviour, and biological balance. Suitable for aquariums from 60 to 100 litres, it features a highly accurate electronic thermostat (±0.25°C precision) to maintain stable water conditions. The shatterproof construction ensures durability and safety, making it ideal for sensitive planted aquarium setups, shrimp tanks, and community aquariums requiring consistent and intelligent temperature control.
