    • Works Great!
Size: 1000W (for 105-238 gallon)
I bought this for use when making salt water in a 40-gallon trash can. It works great! I have a RO/DI system in the house which takes a couple hours to fill the can. I plug this in as soon as the water submerges the heater. It does an excellent job of heating the water as the can fills. The water is always heated to 77 degrees by the time I mix in the salt and am ready for the water change. I love it! ... show more

This is a powerful heater that holds temperature very well. Compared to my marina 100w heater in the photo, it does look rather bulky, but it blends in just fine in my cichlid tank. When I first plugged in the heater, my current temp readout was at 76f and I set it to 80f. It took about an hour to reach 80f, which is fairly quick. My marina heater takes a few hours. The temperature has been holding all day, even in a colder room. My room temp at the moment is 70f, with the window slightly cracked open and the tank is about 3 feet from the window. It kicks in when it's 1 degree lower, which is more ideal for those with sensitive livestock. Some heaters don't kick in until the temp is down to 5f lower than your desired setting! You don't have to worry about wide temperature swings with this unit. I appreciate the exterior temp readout and control module. It comes with a hanging kit and can be secured on the edge of the tank. It does take a few presses to get to your desired setting, because there's only one button. It just cycles through to 93f and starts over. Pressing and holding the button for 5 seconds changes it from F to C readouts. The suction cups are very good quality and didn't give me any trouble, but time will tell. Another thing I appreciate is that it has a memory setting in case the power goes out. I tested it by unplugging and replugging it. The setting always stayed the same. This gives me peace of mind. The only thing I do not like about the exterior module is that it can be easily accessed by kids... and kids love pushing all sorts of buttons... But I am single and don't have to worry about this.. Just be careful and keep an eye on your temp settings when you have kids over! Or better yet, conceal it to the back corner. It does blend well in some setups and may look bulky in others. This is something to consider. Personally for me the housing doesn't bother me. I'm not a big fan of the big glass tubes. My yellow lab cichlids are too big to fit in the slots, so I don't have to worry about any misadventure. I will keep testing this throughout the upcoming season and will update on any changes. ... show more

    • Good quality heater
Size: 500W (for 66-135 gallon)
This is a good heater if you have a big aquarium. I love the controls that hang on the outside of the aquarium, and that it tells you how warm the water at that spot actually is. I had mine at the opposite end of the tank from the heater, and it made me aware of the fact that I needed a powerhead to circulate the water in my tank. ... show more

    • Worked great for while. (update - Replaced free after 9 Months, no Issue)
Size: 200W (for 45-80 gallon)
Does what it supposed to. Stays within 1 deg all the time and I love the digital readout. It might be a bit larger than the usual ones because of the plastic guard on it but I got used to it and it looks great now in the tank. Make sure to clean it out, it gets very dirty inside that plastic housing. UPDATE: After 9 months it died, shows EE and I cannot fix it. Tried cleaning it , let it dry out, Unplugged it for a day. Nothing, It will show the proper temp for about 3 mins then "EE" and it shuts off... Poor fish got cold. Looks like the warranty is 1 year? I Lowered the rating from 5 to 2 . Contacting Vendor, I'll update UPDATE- After contacting the Vendor and telling them the issue, they immediately sent a new heater, It was here in 5 days. Very impressed. I raised the star rating to 4 from 2 due to the customer service. Let's see how long this one lasts. ... show more

    • worked great for 2 weeks then catastrophically failed in a very bad way
Size: 200W (for 45-80 gallon)
I bought the 200 watt version of this heater for my 29 gallon aquarium and it malfunctioned after 2 weeks. Came home to find that the water looked cloudy. The display indicated that the unit was set to heat the water to 81f and that the temperature of the water was 78f. Put my hand in the water, clearly not 78f. I temped the water with a digital thermometer that I know to be 100% accurate and found the water to be at 95f. I was expecting this heater to be reliable because of its digital controls and its advertising that boasted about its accuracy and reliability because of its its dual temperature probes. It specifically mentioned that if a temperature probe failed it would not keep heating up the water --- “If one of the probes is broken, the entire heating rod will stop working. There is a double insurance to prevent the probe from being broken and the heating rod will continue to heat up”---. I should also point out that the advertising of this heater indicates that it has an over temperature alarm which never went off on my unit because the electronics on this thing couldn’t even tell that the water was hotter than 78f. The heating element was basically on 24/7 because the heater thought the water was at 78f when in reality it had already heated the water up into the 90’s. I recommend that nobody buy a heater over 100 watts unless it is really required for your setup to reach the temperature you want. That way if it fails there is less of a chance of it heating up your aquarium to unsafe temperature levels. ... show more
