Review: ⭐️⭐️⭐️⭐️⭐️ Precise, stable heating with excellent safety features - The Fluval E200 electronic heater has been rock solid in my aquarium. What really sets it apart is the temperature stability and accuracy. Once set, it maintains the water temperature extremely well without noticeable swings, which is critical for fish health. The digital display is clear and easy to read, and I appreciate being able to adjust the temperature precisely instead of guessing with a dial. The heater reacts quickly when the temperature drops and shuts off properly once the target range is reached. Build quality feels premium and well thought out. The protective casing adds peace of mind, especially in tanks with active fish. It also feels safer than traditional glass heaters thanks to its internal safety features. Pros: • Very accurate temperature control • Clear digital display • Stable heating with minimal fluctuation • Strong safety design and quality build • Ideal for medium to larger aquariums Cons: • Higher price than basic heaters • Takes a bit of space in smaller tanks Overall, this is a reliable, high-quality heater that’s worth the investment if you care about consistency and safety. Perfect for anyone upgrading from basic heaters or running a larger, more sensitive setup.
Review: Excellent heater - When I upgraded my aquarium from a 25 gallon high to a 30 gallon my old E100 was no longer powerful enough (despite the E100 indicating it was good up to 30 gallons). I purchased a E200 which works great. This is an excellent heater that is easy to set and monitor. Note: the digital display on the E200 that was sent was faulty and so I returned it and the replacement has no issues.

### ⭐⭐⭐⭐⭐ Works great in my 55 gallon Village. Easily raises temp and communicates well.
*by H***. on April 13, 2013*

I have been using this product for about 4 months and it has worked great. I got this one compared to the E200 just because it was a buck or two more. I have a 55 gallon Texas Map Turtles / Guppy Kingdom / and some lucky large snails. The E300 says it's made for anything 100 gallon and under so it handles my task well. I have read other negative reviews about this heater from people using tanks over 100 and even 150 gallon and even installing it wrong....if you read and follow directions this will work for you. I like the casing it has around it so no animal or anything can get close to the heat tube. It had suction cups that attach directly to the heat casing and they suction really well. I have not had to move mine at all even though I have 4 ninja turtle climbing and jumping off of it hourly. So structure wise its made pretty well. As far as heating the tank it has met my needs. I know this from a couple things. I also use some old school suction cup mercury thermometers and they are in line with the correct temp readings. Also since I had hatchlings I wanted to raise my temp to 81 instead of the 77 it was staying at (I got it in december the cold months remember) it always kept it at 81 and now that the warm has come and there has been some really nice days I appreciate it even more because it flashes a differerent color and lets me know the tank is higher than the level I wanted it at. I set it for 81 but the sunny day made it a lil higher so it let me know. I clicked it down to 78 and it does the job still. I'm going to buy another one for my 75 gallon tank eventually. I will let you know how it performs for 75 gallons maybe at another time but for a 55 gallon it has worked perfect. It may work well for me because I have a tank 100 gallon and under. i positioned it under the water with just the temp. change click showing a little but you can put it deeper if you like (thats what sh....ahhh never mind) and I also put it in the path of my cannister filter flow out put. Heaters and filter work better with water flow not stagnant. This is what has worked well for me. I also might add I am using a cascade 1000 and two cascade 600's so I have constant water movement in the tank and on the heater. Like I said before water movement helps heating and filtration. For me....
