Review on Cylindrical heater AQUAEL ULTRA HEATER 75W (35-75 l) 75 W by Dagmara Rudowska ᠌

Excellent heater. I took a 60 l aquarium, it keeps the temperature perfectly. My growing albino thorns are delighted. Water from 19 to 25 degrees warmed up in 1-1.5 hours. The suction cups hold well, it is very difficult to unstick from the wall to move. As you know, thorns are quite active, so the plastic case is a definite plus, besides, the heater is much thinner than other models - it does not take up much space in the aquarium and does not interfere with the fish.
