Mini Fluval Marina Submersible Aquarium Heater: Effective Heating Solution for Fish Tanks Review

I bought a 5 gallon Fluval (Fluval Spec V Aquarium Kit, 5 gallon) and the reviews say it's difficult to find a heater. which matches the design of the tank, but this heater has been offered on several occasions. I had the heater on for several days, it didn't work - the water temp was constantly 70 degrees or colder. I thought it was user error, I checked and the water was above the minimum water level line, took it out, no it's warm, yes it's completely inside out. I thought - maybe it's a…

While I love the fact that this heater fits my Fluval Spec V perfectly, I haven't had any luck with it.

I turned the heater all the way on and it can handle a miserable 74 degrees in a 68 degree room. UPDATE July 2019: I broke the heater described above (my fault) and ordered another one (actually two as I will be installing another 5g aquarium…

I was looking for a compact aquarium heater that would insert into the filter outlet of my Fluval Spec V (5 gallon) tank without being visible in the main body of the Tanks, but my choices were similar to the $22-$25 black plastic non-adjustable Fluval/Marina body, the $20 Hydor heater with no guard on the radiator, or the $28 EHEIM.
