  • It works
Pattern Name: 50W
First time I used it temp went above 80. I had it set at 76. Turned it off, let the tank cool down, restarted it. Seems to be working fine. Maybe I didn't read it correctly, All good!!

  • Good quality !!

Bought 3 for my turtles . They work great for what I needed them for . They have to be fully submerged or will burn up . I made that mistake the first time I bought one that I didn't submerge the heater . Very easy to install . My tank is 100 gallon and keeps the water warm and comfortable for the turtles . Very pleased with the heaters . ... show more

  • Heats to correct temperature
Pattern Name: 300W
I have had a number of tank heaters and it’s always a fight to figure out where to set it so that the water matches the set temp. I am never successful and have to be so careful to watch the water temp or fear killing my fish. This heater was set and forget. Works perfectly!

  • DO NOT BUY - FIRE HAZARD - MELTED IN MY TANK - FISH ALL GONE
Pattern Name: 50W
PLEASE DO NOT BUY THIS! I just had a devastating loss in my tank because this thing decided it wanted to get hot and melt all all the plastic clips. It probably shocked my entire tank! I just did a water change on my 10 gallon tank. I always shut down my heater, filter, and air bubblers. Once the water gets high enough to cover the heater, I start everything up again. Jesus, I had just put the last gallon of water in the tank and all I could see was smoke. I thought it was my light, but it was coming out of the water because everything was melting. I switched the main power button on my surge protector. My fish started flopping and sinking to the bottom. I had a net that I was able to catch a few tetra fish that were at the top. My shrimp darted to the top of the tank, then nose dived to the bottom and turned upside down. I am so upset right now. I just lost 5 fish and a dozen shrimps. Probably will lose my assassin snails and two other tetra fish that I was able to get out of my tank. I have several pest snails that are now laying on their sides that will probably die. But those are not such a big deal. I spent nearly 6 months on this tank getting everything right. I just didn't have a heater, and opted for this one because of all the "Wonderful Reviews". Don't do it people. I am adding photos, not of my fish that were loss. ... show more
