Fluval T300 Fully Electronic Heater for Freshwater Aquariums up to 80 Gal.

This has been working perfectly. Really appreciate the light being blue or red, but always on, as you know if it's broken or somehow lost power at a glance. The heating keeps it easily within 0.5C of the target with no issues in our 240L tank. It installed wimply and the suction cups have been reliable so far. We did have to return and reorder the first time, as the initial one we recieved died after a few seconds of use, the replacement has been fine.

Brilliant and stylish heater. Really good temperature control and love the colour changing light. I always used EHEIM, but never again! Love this!

Great heater would have given it 5 stars if the silly black dot to set temperature was say a white dot so could actually see what temperature you had set more easily but black dot on black background come how easy would been to make that more visible, not a Biggie you just have to waterproof paint and do it yourself, other than that good heater

Great Heater I always use Fluval heaters in my tanks as they work perfectly and last for years Sleek black design looks great they are rather large tho but easily hidden with decor Not to expensive either pretty good price from a reputable brand Would Highly recommend Will be buying another for my other tank

Great product

Fabulous heater, well worth the slight extra cost. Being able to mount it horizontally is a godsend as it's now completely hidden behind the rocks and plants so the tank looks far less cluttered. My previous cheap heater allowed the temperature to drop by 1 degree before switching on and then raising the temperature 1 degree above my setting before switching itself off. The electronic system in the Fluval has much finer parameters and accuracy, seems to come on at 0.1⁰ below and switch off again at exactly the temperature I've set it to. It's held a set temperature of 25.5⁰ for 10 days solid without more than a very occasional 0.1⁰ downward fluctuation shown on either my digital internal probe or standard thermometer. The fish definitely appear happier and healthier without the large temperature swings. The permanently illuminated power & heating light ring gives peace of mind that it's working at a glance. I have a second tank and will definitely replace that heater with a Fluval when the original that came with it starts to misbehave.

Worked great for 8months then just died. Waste of time and money.

Brilliant very stable temperature nice blue or red light very cleary

I bought two of these for my 120 gallon. I always use two smaller heaters, because I've had many heaters stick on and I'd rather have an undersized heater making the tank warm, rather than have a "proper" sized heater cook fish.

So far so good . Love the design. Simple , efficient. Has good features. Avoids problems like overheating, bursting and overall good product.

Dégoûté, j'attends avec impatience ce chauffage car le mien est très irrégulier, déjà il n'arrive pas au moment marqué sur le site Amazon, après il est perdu , après il part à la poste , et finalement quand j'ai réussit à le récupérer, il a une prise ANGLAISE 😑😑😑😑‼️ Donc je doit attendre encore 3 jours pour avoir un adaptateur, bravo prime ‼️ Pour le produit, c'est a voir dans le temps mais il semble résistant à la première vue .

looks nice and works great I like the color indicator very goexcellentt

I've had many heaters over the years. I like how this is so easy to see if it's on or off. No condensation in the housing so its truly a submersible heater. Bit big for my 10g tank as it's quite long bit still fits and works great.
