Review on 🐠 BOEESPAT Small Aquarium Heater: Efficient 50W/75W/100W Heater for 5/10/20 Gallons Betta Fish Tanks with LED Temperature Controller and Smart Thermostat by Matt Pratt

Amazing heating! A must have item for any cold tank. I've had this heater in my aquarium for over 24 hours 48 hours and look how crystal clear it is. I don't know how or why it's so clear heat is supposed to inhibit microbial growth. My tank went from foggy and smelly, needed cleaning every 1-3 days, to crystal clear. I've been comparing heaters on Amazon while reading reviews and worried about buying a heater that will kill my fish or heat them to high temperatures. It took two seconds to set it up, you take it out of the box and plug it in. First let it measure the water temperature, it will beep/flash and then display the actual water temperature (I suggest cleaning your aquarium before using the heater which I did) and after it displays the temperature, am At the end of the next wire there is a button with the plug, press it and set the preferred temperature, 78 is the pet store's recommendation, but after cleaning the aquarium I accidentally poured too much warm water, so at 80 degrees my fish were swimming and they went from hiding in rocks and hiding everywhere and being inactive and cold to flying in the aquarium and being active 24 hours a day, 7 days a week. and so happy! This is an amazing heater, I've never used one so it's perfect for beginners! The light stays green when working. When the indicator turns red, it means the tank is heating up. So think of red as HOT - heating. My aquarium has never been so crystal clear. I have a Revain plastic tank that I got for 39.99. Tank for Koller products. 5 gallon ALL in one starter kit including filter. I recommend this tank from Revain, this heater is made in China but for those who don't buy things made in the USA. This heater has two suction cups that suck very well right after a dive. Make sure the heater is completely submerged in water. The cable will not electrocute your fish. This heater is safe and appears to be temperature accurate. You can put this heater anywhere as long as the heating cable is about 1 inch underwater, and even put it on the bottom of the aquarium with the cable coming out the far left or right. You can put it on the floor, but it must be free of decorations. I suggest placing it vertically and in a corner where the number is clearly visible. 5 Stars.
