Heaters are one of the most important pieces of equipment for your aquarium, as they provide a stable temperature for our aquatic pals. Fish and other aquatic species do not produce body heat, so their well-being is related to the temperature they are kept. Temperature swings are known to cause stress within the aquatic environment and its inhabitants, so heaters are key to keeping them happy, healthy, comfortable, and can inspire some species to spawn or reproduce (at specific temperatures).
Finnex Titanium Heaters will maintain water within 2 degrees Fahrenheit of the set value. The titanium construction also is corrosion resistant, making the one of the most durable heaters in the hobby.

You could use a 150W heater for your 55g tank or if you want redundancy you could use two 75W heaters that way if one fails on the remaining heater won't be able to overheat your tank.
CONS
Do not try to use two of these next to each other

I tried the controller ran finned this time on my apex vs the ones without that I usually use. The heat would not get accurate which I believe is because they were next to each other in the sump skewing the heat readings. I took off the new ones, out the old heaters back on and will buy the non controlled ones as they are much more accurate with the apex. I will buy 2 external controllers as wellHide
PROS
Accurate temp, compact size, controller is out of the water which makes adjusting easy.
CONS
None so far, 3 weeks into use.
REVIEW
Great little heater. Placed in my Discus tank and hold the temp right at 85 degrees as set.Priced very affordable and plan on ordering another for back up.
Works very well. Heats 30 gallons of salt mixing water very quickly. Is quiet, and I like the idea of the external control - is especially easy to read. Like others have noted, the power cable is extremely short, but it is as-advertised, and not too big of a hassle.
PROS
Low cost, highly reliable, accuracy within specification
CONS
Have not found any cons to this heater.
REVIEW
I purchased mine March 2018 for my reef tank. I have had zero issues with my 300w. My tank is 90 gallon with a 40 gallon sump that keeps 23 gallons in while running. Thermostat control is set to 81 f and keeps my tank a 79.8 with no fluctuation. It is easily one of the best heaters I ever bought.
