Buy another brand... By Hack21 on 3/26/13

I purchased the HMA-500 Finnex Heater for my 120 reef tank. The pros are the external controller, titanium tube, and the length. But that is where it all comes to an end.
I ordered my first unit in November of 2011, and it had to be set at 87 to maintain the tank at 78. Wasn't very comforting so Bulk Reef Supply did replace it in early December.
The replacement unit worked great throughout the winter, I turned it off cleaned it up and stored it for the summer, and got it back working again in the fall of 2012. All was fine until two days ago when it would no longer heat. The controller light comes on but no heat from the tube.
I contacted Finnex and they responded in less then 24 hours so no complaints there. But this product has just a 6 month warranty and paying to have it serviced based upon their track record seems foolish. I am of the opinion that poor performance, poor quality, and a short lifespan is the standard for products made in China. No wonder it only comes with a 6 month warranty.
Funny, I have a lower wattage (300w) glass tube model from a manufacturer Bulk Reef Supply does not sell that I typically use just to heat up water changes and it is handling the job just fine. I paid just 16.00 from another site, and I ordered a second one today. So buy a cheap heater since that mirrors their quality, and buy a good controller since they will fail. That would be my recommendation.

Awful heater, bought an HMA-500 for a 90 gal reef tank. Will not stay on, it comes on for a few seconds and goes off again. I really should have paid more attention to the reviews.

I bought this product because I was tired of always adjusting my heater 5 times a day. I placed this heater in my sump and the controller mounted nicely inside my stand. Love it.

While some have reported issues with these, I am happy so far. I have 3 of the 200w versions and a 75w one. All are still working great for 6 months now.

Works well By Mike on 8/30/12

I've been using 4 of these (2 150's & 2 300's) for about a year they have held up and work just fine. I like that I don't have to worry about breaking them since they aren't glass tubes. I've noticed they aren't perfectly calibrated, so the temp you set it for might not be exactly what you get, but that's not really an issue. Use a thermometer (or several) to make sure you're at a good point and then just use the dial for adjustments. Nice to not have to get my hands wet.

Bought 100 w for use in 20L tank in fish room. Is very compact to fit well in short tank. Have not had any issues for over a year. Have had some problems with glass tube style of Finnex heaters so would recommend with caution.

As the title says all of the heaters failed. The support refused to provide a RMA. This is the worst purchase in my 15 years of reefing.

Bought 3 300 Watt Units By Rocco on 2/5/12

I built a new custom setup with a high flow sump. I originally planned on only placing two into the setup however 2 wasn't putting out enough heat to maintain a 80 temp when temps were down in the 40's. With the 3rd things are great. Haven't had any issues and going on 2 months now.
