I purchased the 500w heater and after 4 1/2 months it started to shock me when I put my hand in the tank I got ahold of finnex and they told be if the damage was due to water I would have to pay for the repair and the shipping back to me. on top of paying to ship it to them . I thought Heaters were to go in water. will never buy again

I bought two of these for my 220 gal reef build.
upon putting them in my sump and plugging them in. BOTH leaked current badly. Putting my hand in the water to move them in the sump and I could feel the current in the water. touching each one gave me a very nice shock.
Total chinese junk. If this is how bad their quality control is, they dont need to be selling merchandise to the public.

I purchased the 800W version of this heater for my 210 gallon tank. The heater works very fast and keeps the temperature stable. I have it hooked up to my Apex Controller. I think it is a great heater for the price.
BUYER BEWARE!!! By Jon on 3/25/2014

I purchased the 500w heater to use with my apex system in November 2013. In February 2014 I got a shock when I put my hand in the sump. After testing each thing attached to my tank, I found out that it was this heater. Now I know heaters go bad and sometimes we get the bad apple that doesn't last as long as they should. So no big deal other than the shock could have been worse. Since the order was more than 60days BRS couldn't do anything about the heater, that's understandable. So I contacted the manufacturer. They told me that it was out of warranty. WHAT? it's only been 90 days! What's what the warranty is for this heater! So beware. I switched to a different manufacturer for this reason.

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!
Just Works By James on 1/14/2014

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.
Great Heater By Michael on 12/30/2013

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 11/5/2013

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.
now i got 2 of them By Tim on 7/14/2013

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 5/13/2013
David wouldn't recommend this product to a friend
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 4/19/2013
jeremy wouldn't recommend this product to a friend
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.
Works Well By RLDCPA on 3/31/2013

I originally bought another brand of heaters (2 300w heaters with a thermostat) but they were not enough for my 230 gallon tank. So I bought this Finnex 800 watt model and has worked great with my Neptune controller.
As these are fairly inexpensive as they have no thermostat in them, I bought another and put it in another compartment of my sump. I figure 2 will be safer if on ever fails. And the Neptune Apex logs your power usage so I will now exactly when it fails if it does.
If feel that using a controller is the way to go rather than a thermostat built in to the heater and cheaper in the end anyway.

I have this on my RKL running in the sump of a 100 gallon system, 75 main, 25 sump. My previous heater of a different brand was leaking current. This one isn't having any detectible excessive current leak. So, that alone make me happy. Over time, we will see how this unit works.

Installed 500W on 120G display with 40G sump. Using Reef Keeper Lite as the controller, it maintains constant temp within 0.1 degree Fahrenheit. Running less than a month, but so far so good. If it lasts, then it will be a 5 star purchase.

500 watt Heater worked just fine for about 8 months. Not what I would describe as a "deluxe" heater.

I am heading into my first winter with a freshwater discus tank at 83F. I needed good heaters instead of the 6 random ones I had laying around. I have 2 800 watt heaters in the sump connected to my apex. If you can hook up to a controller instead of buying the one for it, It is a great deal at 50 dollars. So far this has been a great heater. I will be interested to to see how long they last.
