🐠 PGFUNNY 25W Aquarium Heater, Smart Thermostat Fish Tank Heater for Betta, Slim Design Fits 3 to 5 Gallon Tanks, with Thermometer Strips Review

Beautiful, slim design with powerful suction devices, they stay and won't move until you pry them open. At 3.5 gallons the temp is a constant 82 and never goes up or down. Henry has a lot of energy. He was really active at 75, but now at 82 he's even wilder! If anything new happens I'll update the review, but for now everything looks good!

Perfect for my 3.5 gallon aquarium where I keep Betta. Slim and handsome compared to some heaters, it is not bulky. This keeps my 3.5 gallon bettas at around 80 degrees. this is ideal for fighting fish. I saw him between the ages of 78 and 82. The little timeline they give you isn't the most accurate, you have to slide your finger across it to see the reading, but it does keep the water in the tank nice and warm. It also has a red indicator light that lights up when it's actually heating the…

Purchased for MarineLand 3g Contour Tank. I put it in water for the first time yesterday and let it sit for about 6 hours. When I got home the temperature was 84.7 degrees. I immediately put a fan in the direction of the tank to cool the temperature. Once the temperature dropped to 83.4, the heater turned on and began heating the tank again. You don't want your tank running that hot! This means it is suitable for tanks up to 5 gallons. I think it's for a 5 gallon tank or more. Buying a 5 gallon

Used in my 5 gallon Marineland. I put it in a hidden filter housing and it's so small it fits perfectly. Keeps the tank at a stable level of 77/78 degrees. There is no temperature control, it turns off automatically when the tank reaches 78. Comes with a thermometer and so far works great for my planted nano tank. Fish and plants thrive. It has suction cups. So if you put it directly in the aquarium instead of hiding it in a filter housing like I did, it's small enough that it won't ruin the…

The product is supplied pre-assembled and is easy to attach to the aquarium with or without water. It gradually warms up my 2.5-3 gallon tank, which is best for fish, and the thermometer mounted on the opposite side reads very clearly. The red light indicates whether the heater is active. Sometimes I do a partial tank cleaning and try to remove the heater, the bottom suction cup stays attached to the tank while the heater slides out, but that's a minor inconvenience, not worth removing the…

I've been back and forth about buying this for weeks because of the reviews. I was so skeptical and genuinely afraid it would kill my fish. We have a beta and it's in a 3.5 gallon tank. He was very lethargic before warming up (he lived with me for a good 5 months and he never knew how to swim) - he stayed on his tank near the filter. Before installing the heater, I check the temperature with a digital thermometer, which I also purchased from Revain (about $8). The water was 66 - a heating pad…

Product works as advertised. I treat this fish like my adopted child and share parenting responsibilities with my girlfriend. Ducky often got stuck in a cold bowl and appeared very lethargic in his behavior. After some research (aka Google) I found that the water temperature needs to be maintained at a consistently higher level for bettas to thrive. So I gave up that drab bowl for a small tank, water filter and heater. The difference between day and night. The Blu has many more sailing options.

Just arrived a few hours ago and installed it straight away. The TWO that my wife sold (after going back to buy another one after discovering the first one didn't have a thermostat) also didn't have a thermostat to regulate the heat and turn off the heat when they did was not needed. It was from a known network. with their"specialists". We came back and they looked at me like I had two heads. I am an electronics engineer, over 40 years old. Power is my specialty. It does what YOU WANT and NEED.
