great heater just off a few degrees By turbotone on MR on 12/15/13turbotone on MR would recommend this product to a friendi purchased a few of these heaters due to the fact they are titanium and won't break which eliminates one of the common failure with heaters.. i own 2 150watts with controllers both used for my 20 gallon tall tanks (one for make up water the other for quarantine) 3 200 watt with controllers 2 for my 90 display 30 sump setup (one in the return chamber and one in the first chamber) not really necessary but i like to be redundant as the set up is not a tech tank but very simple.. the other 200watt is just a spare.. then for my 120 build tech build I'm planning on using 2 300 watts without controller bc I'm planning on monitoring the temp off my neptunes controller..
with all the heater with controllers that i have owned the temperature reading has been off by 4 degrees (3.8 degrees to be exact) so to keep my display at 78 i set the temp on the controller to 74 degrees.. same goes for my 20 gallons.. these heaters are strong so rule of go 1 size bigger is definitely not needed.. stick with correct size on the chart.. my 150 watt heater brings up 65 degree of rodi water in the 20 gallon tank to 78 in about 2 hrs tops.. i think 2 150s would be ideal for my 90 dt and 2 200watts for my my 120 would be better which i might do being my heater rarely cuts on like then anyway.. again one of the heaters might be ok i use two to be redundant..
i gave it 4 stars bc the compensation of degrees that needs to be done but really its not that serious.. would get 5 stars if the temp read perfect.. will tune in next december 2104 to give an update on the heaters..
WORKS GREAT but Temp is off. By Eric on 12/15/13Eric would recommend this product to a friendHeated my 27g cube quickly from my sump. The remote temperature prob is great but the cord length is a bit short. It just barely made it to my display from my sump. The temperature setting is about 3 degrees high from the set point as well.
Built in Thermostat
Remote Temp Prob
Thermostat is off -3 degrees
Great Product By Jeremy on 12/11/13Jeremy would recommend this product to a friendWorks great. I had my eye on another heater that wasn't as good and when I called in to ask about it the guy I talked to pointed me in the right direction. I ended up taking his advice and ordering this heater. It worked perfectly straight out of the box. Like many other reviews have said it is off by about two degrees but I plugged the heater into my Apex and the apex controls when the heater comes on and off, which crushed the degree issue. Good Product
Jacuzzi By Travis on 12/5/13Travis would recommend this product to a friendThis heater is simple to use and super trustworthy. It is all metal, and it has an alarm for low and high water temperatures. If you hear a beep, it's time to run to your tank! I haven't had a problem with it, and it is easy to read from across the room. The only thing I had any problems with were the directions! lol
Great Heater By Brian on 9/25/13Brian would recommend this product to a friendI bought a 200watt for my 60 gal and it is keeping my temp at 78 with no problems. I will probably buy another just so that I have a backup in my tank. Redundancy, redundancy, redundancy.
Good Heater By Steve c on 9/12/13Steve c would recommend this product to a friendOnly problem it is off by 4 degrees says on the heater 74 and my tank is 78.
Heats up fast By Sal on 7/21/13Sal would recommend this product to a friendI bought two of these heaters and it gets the tank temp fast and maintains it well
Excellent Choice By KRaney on 6/4/13KRaney would recommend this product to a friendSo far so good. I am loving this heater. It is what it is and does what its supposed to do so I am not going to nit pick it to death. It works and works great!
Hot! By Dan on 5/11/13Dan would recommend this product to a friendGood heater so far! Keeping the temp at 78F. Has an annoying alarm and you will most definitely know if something isn't right.
Consider if not using a controller By Starrme on 4/29/13Starrme would recommend this product to a friendOverall: Bought this as my first heater and have already replaced for my main tank. The digital display isn't a major benefit to me because I am using a controller. I will continue to use for heating my water change SW.
- Lights up when heating
- Digital temp setting and display
- Read out is on outside of tank
- Has separate temp measurement probe
- Makes a loud beeping noise when initially placed in cold water.
- Metal hooks to hold display too narrow for my sump rim
- Digital display is bulky
- Accurate to within 2 degrees
Note: If temp is significantly out of range, the heater will beep continuously. I thought my heater was broken when this first happened. The beeping is a warning mechanism for if the heater fails but is a major pain when using to heat up new ro/di water.
Easy Set Up Easy Read By Alexandria on 4/19/13Alexandria would recommend this product to a friendThis was super easy to set up and I like the digital read out. No more squinting on the old timey thermometers. Got the JBJ Digital thermometer with this. They are about 2 degrees off from each other. However, the JBJ digital thermometer is reading the same as the old timey thermometer so I trust the new digital thermometer and will set the heater 2 degrees up or down as needed.
Also impressed by how small it is. So in a small tank it's not this big honking thing that's getting in the way. If you have a small area for your heater this would be the way to go.
Will update as we go to see if there are any problems.
Ehhhh... By Michael on 4/10/13Michael would recommend this product to a friendBought two of these, one is still working flawlessly. Plugged in the second one the other day and it made an awful hissing sound like some sort of gas was escaping through the rubber ends and I noticed a weird smell. Not sure what happened, contacted finnex to see what they can do.

Do have a controller that controls both the heater and the chiller ??
Bulk Reef Supply Hey Ed,
For something like that you would be best served by an aquarium controller. The most basic of which is the Reef Keeper Lite unit and it will do both of those things as well as give you two more outlets you can use as timers or other functions.

IF MY TANK IS 60 GALLONS WOULD YOU RECOMMEND THE HMO-150 OR HMO-200?
Bulk Reef Supply For a 60g tank we would suggest using the 200w heater. Its best to err on the larger size in case you need it (say you have a particularly chilly day).
