Hydor 7W Mini Submers Heater

Customer reviews for 'MINI HEATER Aquarium Heater 7.5W for Tanks up to 5 Gallons UL'

Worthless; only raises temp a few degrees - not worth it

Bought this for a 5.5 gallon tank with over 1 gallon of substrate, thinking that the heater would be capable of heating the water to the 'consistent 78 degrees' as stated by another online retailer.

Quickly I realized this heater was not going to get the job done. As I read into it more, I found that some retailers list this heater as designed for a temperature increase of 3-4 degrees above the room temperature.

For me, this is pretty worthless. I don't want my water temperature dependent on my room temperature, nor do I think the cost of the heater and electricity is worth it for a measly 3 or 4 degrees.

Hot, hot, hot!

I purchased this for a 2.5 minibow aquarium and found that if you leave the light on ASWELL as the heater it can cause a BIG temperature jump. I mention this because my betta really got stressed from all that heat the first day - I think he got a little sick because of his clamped fins and lethargy the next day. So be careful that the heater doesn't overheat your aquarium/bowl. My idea is to leave it on at night and then turn it off during the day so that the light can maintain the aquarium at a few degrees lower, it's the best option without a 15 watt automatic shut off heater in a 5 gallon aquarium, which is probably what I will do when I can afford it next month! Good luck:0)

Perfect heater

I have a 2.5 gallon acrylic tropical tank. I use this tank heater only in the winter when our ambient house temperature is lower. It does a stellar job keeping the water a steady 72 degrees.

It's small, easy to hide and reliable.

I highly recommend it for small tanks when only a few degrees increase are needed.
