@@coleshafer6879 it will heat up in time unless the heater isn't strong enough for your size tank or the tank may be at 80 and therefore the heater won't come on until temp drops you may need rwo heaters if you have a large tank
@ReBootEnzo, the required heating power is usually 5 watts per gallon. If the ambient temperature of your room is very cool, it would be the power requirement of your heater. You also need to ensure that there is good water movement around the heater as this can dramatically impact how efficiently it functions.
I love these Fluval heaters. I own the 100 watt and 200 watt heaters. I will definitely get the 300 watt once I upgrade my tank. I have no negative feedback on these heaters.
Hi, knowing the ambient temperature is an important consideration as well since it takes much more energy to maintain a temperature of 26°C at 20°C ambient vs. 25°C ambient, for example. That said, a 100 W heater is recommended. Also, take care to protect it from the turtles as it's not uncommon for large turtles to cause breakage to submersed heaters. Hope this helps!
Had around 6 of these now for about 20 months no faults so far, only just cleaned one (little slime but nothing serious). Both in freshwater turtle tanks (some very large at 200-360 gallon) Work really well. Accurate as well (I have calibrated laser thermometers to check every now and then they are functioning correctly. The water temperature is as the E300's state. That Being said there is definitely room for improvement, these require high flow areas of the tanks, I use Fluval FX6's on all my aquariums and I still had to locate these at an angle in particular places to ensure they don't give the "LF" all the time, I would say maybe a slightly less restrictive guard version might be a good idea for better flow. Also I know these are predominantly for fish but the lever adjustment had to be modified on mine as a 6" turtle is surprisingly heavy and strong, growing potentially up to 14" Straight Carapace length I would have preferred a locking mechanism for the temperature adjuster.
So what do you do if it blinks red or blue ? Just leave it until it returns to normal? Or adjust it? And to do you just flick it to what temp you want and that's it? Do you have to hold it to set it or? Any info would be great thank you
i bought one of these around the time it just released earlier this year; it works well and i like the lcd screen. however, if kept inside a saltwater tank that has typical algae (green hair, coralline, or even red slime) it requires cleaning very frequently so that the inside casing doesn't get clogged, affecting the censor and giving you false read outs. i didn't know this was fully submergable.. is it really? overall i like it!
Can u place the heater in a oblique position if the tank is smaller than the length of the heater? I bought 200 w cuz i m gonna to upgrade the tank at some point, but it is too tall for what i got now.. Thank you
That depends on the tank size, ambient room temperature, water surface to ambient air exposure and power of the heater. The E series requires placement in an area of good water movement due to its protective cage. In general 5 watts per gallon is recommended and would cover average room temperatures and aquarium target temperatures.
Thanks fot the reply the room temperature is 18/19c not 14c ,the aquarium size is 240 L it has a cover it is the juwel Rio Led 240. So u think I should change the heater. Or do you think? Kindly Advise Thank you
Hello, we mentioned a 14C difference between the target you dialed in to the heater and the room temperature. In cooler rooms a minimum of 5 watts per gallon or 3.78L is recommended, given the very warm temperature you wish to maintain and the cool room temperature adding a second 300W heater should suffice.
Ok the same thing I already added 200 w juwel heater and set it to 32 C and I set the Fluval to 32.5C believe me if I tell you since yestarday at around after noon till now the Fluval did not active only half degree more. Thanks
Hi there thank you very much for your advises, ok now I installed two heaters 300 W fluval 300 E and I have order another Fluval 300 E I will recived today, please advise me how should I set up the two of them since it is my first time set up 2 big heater like those one the temperature I need is 32 degree C , so one heater will be set to 32 C and the second heater shall be set to which degree? Please advice me urgent?? Thank you very much
I have the 200 in a 55g for a couple months now have set to 75 degrees and room is set to 70 so now a huge difference. It’s right next to intake of my fluval hob plenty of flow. My problem is it’s consistently in the blue around 73-73.5 for the past week. What’s the deal here..?
Clinton, we recommend placing the heater in the direct path of the filter output, that will create greater circulation around the heater. Let us know if that helped.
I figured it out I moved it away from the air stone a little bit more now it maintains the temp I want. I love fluval products but I wish this heater had a bit more power
Hi there I bought the Eheim Jager 300 w watt but still I like fluval so I want to install them both I will make fluval as secondary heater so the Eheim I will adjusted at 32 degree C please tell me to which degree shall I adjust the Fluval E 300 I need the Fluval to work as support as well as aquarte tempeture reading on the LCD Thanks
This exactly what I did, I added 200 watt Juwel heater and set it to 32 C since yestarday and the Fluval set to 32.5 but still since yestarday till now more than half a days the Fluval just increased to 30.5, I think it is a smooth heater. Any other suggestions. Thanks
hello good video could you please tell me the total length of the heater as wanting to put it in a fluvial flex 34 litre tank which has a 34 cm height thank you
HI I bought The E300 and set my temp desired to 33 C as well I put the heater vertacily and there is a direct water flow facing it , but now all the time is giving blue light and did not reach the desired temperature even not reach 32C keep stuck on 30 C so is this problem the room temp is between 19C and 20 C Please advise since I am planning to take it back and never buy it again . Thanks
Yes, the expectation of maintaining 33C when your room temperature is up to 14 degrees C below is rather severe. What volume is the aquarium? Is there a glass top? Is there ventilation in the room?
Sounds like a great heater but here's a tip Fluval, not everyone wants one for a tropical aquarium, I need one just to prevent my temperate tank going below 18°C on very cold nights so the minimum temperature setting of 20° is no good for me. As easy as that would have been to give it a wider temperature setting range, yet you didn't. Shame. Think outside the box a bit more guys! Now I have to give serious though about whether I want to continually run my tank at 20° especially considering that the accuracy is +/-1° which means it could actually be 21° and that's definitely too high for my requirements! That being said, it is a brilliant piece of kit though.
Hi there! 18°C is well below normal ambient room temperatures - aquarium heaters aren't at all made for those sorts of temperatures. We recommend you turn the heating in your home up a little!
I'm currently using the e200 in my coldwater set up as a back up and it is set to 20 degrees c, in the event of a power cut will this heater remember my setting or will it reset and heat up to the default 25 degrees c?
Try unplugging the unit for a few minutes, then re-plug in and shift to the left. If your water temperature is above the set range, then the unit should be flashing red. When you shift, be deliberate; one clean motion and release and repeat. if this fails, then we'd suggest contacting your retailer (always a good idea to have your proof of purchase with you).
Hi there I have E fluval 300 w and I was setting it to 32 degree C for my discus tank . For medical reasons.

+WILDWELSH Taking the temperature of the room into consideration is good thinking! In this case, 300W is probably a good power level to start with.
