FluvalT300 Fully Electronic Heater for Freshwater Aquariums up to 80 Gal.

I got this t 200 for my 180 liter cube hospital tank Nice chunky little heater I have a t300 in my 4 ft tank about 18 months ago I love these heaters the way the litter blue light comes on so you know it's working then flicks to red for a few seconds. The easy temp selection diel at top no little pine that's impossible to turn.holds a steady temp.Pic 1new t200 just set up lots of air bubbles. Pick t300 on its side worked well upright or horizontal. i will only bye these now I have 5 tanks and will slowly get these t series. Not the cheapest but you do see it in build quality. Lol I genuinely love them.best heaters I have had.

I have 5 tropical tanks and have this of the smaller version in every single one. Hold temperature nicely. Super high quality. And the light on the top is just brilliant.

Very good quality very easy and safe bit on the pricey side however it is definitely good value for money

Looks great during the day. It has a modern and stylish look, with a blue standby light, and a red heating light.The only issue I have with it, is the blue light is quite bright at night. So watching a movie at night, when the heater turns off and the light goes from red to blue, it catches my eye every time. And the light is not directly "facing" me, it lights the tank up a little. So there is a sudden change from subtle red (the nature of red light), to a bight blue. If the light faded from one to the other, I think it would be fine, but the sudden change it quite irritating. I know, this sounds petty, but this is a hobby where aesthetics are very important.

Brilliant as I don’t have to worry about it when doing water changes, turns itself off and back on when level is back up

Very reliable and the indication light makes it very easy to know if it's working the size is perfect for my13 galon very good value for money and the functionality is very good but the sturdiness is not the best it has fallen down before but the Ease of application is so nice compared with other companies

Very easy to set up and has a very handy red and blue light on it that let's you know when the temperature is correct. It took about 5 hours to full heat a 240l tank it looks nice and the temperature control is easy to use. It also has a safety cut out encase it fails

Was fine for 2 weeks. Added over £150 worth of tropical fish to my aquarium, the heater ran fine. Then I got home from work yesterday to find ALL of my fish dead because the temperature had dropped to 18 degrees. I've tried to contact Amazon and the seller but the app takes me in loops. To say I am angry is an understatement. I obviously checked all of the connections and sockets and no problems there, this faulty product has cost me a lot of money, stress and hassle. It will be the last time I ever buy fluval again. If I could swear here, I would.
