Small and powerful! By Jason on 2/7/14

I bought the 300W version and it fits into a tight sump with no issue. You do need to have a controller to use it but that's not a problem for me. You just don't have a redundancy like the heaters that have built in controllers. Well worth it. Heats like a champ!

I've had this heater on my 90 gallon reef for almost a year now. I use my Apex controller to monitor the temperature and turn it on and off. It heats the aquarium very well and hasn't given me any problems. I would recommend this for anyone that has or wants to use a controller to regulate tank temperature.

I just installed this into the sump of my 120 gallon reef and I'm running in on a Reefkeeper Lite system. Works great. Temp is nice and stable.
If you have a controller for your tank, this is the way to go.

Great heater, no glass to worry about breaking and no cheap temp controller that will burn out every year.

I have been running the 500 watt for about 6 months now on my 75 reef. Great heater and no problems to report as of now. Quality product at a great price. The only down fall is it comes with no suction cups. Standard heater suction cups will work and can be had for a few bucks
Better Than Good - Amazing By Goodspies on 11/5/13

I recently put this heater in my sump on my 200 gallon tank and it is AMAZING. I keep our house very cool, especially at night, and this 800w heater has no problem keeping up. Plus, when I do water changes, it brings the tank temperature back up very quickly! Awesome product... just know that it is quite long so if you have a small sump that is divided in any way, take measurements beforehand.

I am using the 500W heating tube with my finnex controller and it ia working well so far. I am keeping a even low temp at night, my daytime temp increase due to MH lighting. Good review at this point, time will tell.

I use 2 of these 800 watt units in my sump on my 245 gallon tank and it handles it with ease even in the winter. I use them with the Neptune Apex to control the temperature perfectly.
I have had no issues with these so far and my tank is 8 months old.

I have had the 500w heating my 225 gal folwlr tank for over a year. not a problem. just bought the 300w for my 50 gal reef i'm starting. Hoping for the same dependablity. You should know they need a controller, my D.A. RKE works great with it. Love you guys at BRS. Now get out of my state soi don't have to pay taxes. lol
Mixed Review By David on 5/13/13

I have purcahed several of these in the last few years. Up until the last two, I would count them as reliable. The first lasted nearly 3 years between two systems. The last two have lasted less than 6 months combined. These would be awesome probes otherwise.
Luckily no major problems, though the first time around, it took me some time to track down the issues I was seeing in the tank as temp related. When I checked the controller log, there was a very wide temp swing overnight and 3 degree gap between optimal and high temp during the day.
Nearly KILLED me, FINNEX won't replace! By jeremy on 4/19/13

This item malfunctioned and released electricity into my sump within 2 weeks of use. It shocked me pretty bad. I tested it a few times to make sure it was the heater and I recreated it each time. I contact Finnex and mailed it in to them which cost me $18.
They refused to replace the heater because it tested "within spec" whatever that means. I am out $58 due to this AWFUL product.
DANGER --- DO NOT BUY FROM FINNEX!!!!

It's too early to tell on overall life, but the unit seems well built and works great with my RKL.
