Good product from Fluvsl

I generally don't leave reviews for products, even ones I love, but I wanted to clear up an issue people were having with this heater in comparison to others.The temperature indication is spot on, very accurate. The design is sleek and well constructed. The issue I was having with this unit was not being able to maintain tank temperature in a very cold room, even though I oversized the wattage/gallons ratio by over double the recommended specifications. I believe the shrouding around the glass mildly hinders heat distribution so it is important that this unit gets adequate flow from the filter.I placed the heater directly under my filter return but still randomly had scenarios where the temperature dropped and stayed in the blue, even for a couple days. Then it would rise to green and maintain no problem. What I realized over time was whenever I did water changes or added water, the temperature dropped that night, even if the water added was warmer than the tank water. As the water level dropped over the next few days from evaporation, the temperature rose back up to normal.My hypothesis: If the water level in the tank is a hair too high, there is less disturbance created from the filter return, even though you are still achieving the same turnover rate. Try either lowering the water level in half inch increments until the temperature is able to maintain, or try rotating the heater sideways to achieve more flow through the shrouding. I recommend the first option because turning the heater sideways looks ridiculous with the digital display.I now maintain 77-78 degrees constantly in a 55 degree room and would purchase this heater again. Fluval makes excellent products.

Not only is this one of the best heaters out there with an advanced display, but it indicates when the water flow has slowed to the point of impacting heat distribution.All temperature control aside, I find this to be an incredibly useful feature for overall aquarium maintenance. If my temp display ever turns red/low-flow, it basically means it’s time to service my filter. It has become restricted and isn’t turning the water over as it should anymore.I am committed to proper aquarium maintenance. That said, I have plenty of better things to do than clean filters that don’t need cleaning. Thanks for the smart clean filter notification Fluval!!!

He seguido varias veces las instrucciones y se queda en azul siempre. Un calentador mas sencillo en la misma ubicación y funciona perfecto.Lo dejé toda una noche a 27 grados y por poco se me mueren todos los peces.

Mi spiace per fluval che solitamente ha buoni prodotti. Non so da che cosa derivi il non funzionamento del prodotto, amazon lo spedisce nella sua confezione con un pezzo di carta per tenerlo fermo e forse non basta....... è il secondo che provo e non funziona....... con il led blu dovrebbe scaldare, ma il prodotto non scalda l'acqua, che può quindi scendere a temperatura ambiente ben sotto i 26 gradi che indica il display probabilmente in tilt.Quando parte scalda e arriva alla luce verde, ma invece di fermarsi continua a scaldare e il rosso scatta solo dopo i 30 gradi..... praticamente in una giornata una vasca passa dai 22 gradi della temperatura ambiente a quasi 31 gradi...... praticamente funziona a random.......

great product works excellent
