Heater for small aquariums, HT-330XD model. This was used in a reptile greenhouse. It allows you to set both a lower and upper temperature limit, so I used it with peace of mind. I switched to air conditioning because the number of animals increased, so it was only used for one season. A mini ceramic fan heater is also included. Please comment if you don't need it. I will discount it by 500 yen. - Model name: HT-330XD - Power supply: AC 100V 50/60Hz - Applicable temperature range: 15℃～40℃ - Brand name: HYDRA Thank you for viewing.
