Fluval E Series

[Ronnie27]

Hi again, as some of you may know i am getting a 350ltr tank and will be running a fluval fx5 filter. But now my questions are about heaters would the Fluval E Series 300w be powerfull enough as it states thats its for 375ltr tanks or is it like the filters where you should always go bigger than the box states? thanks adam

That will be fine on that tank. Although alot of people prefer to have 2 smaller heaters in a large tank say 2 x 200w. So if one fails you have a backup, and if one sticks on you have more time to notice before your fish cook.

i own a fluval e heater and i have found it very under powered through the cold snap we had recently i was waking up to find it had lost between 2-4c over night it would then take most of the day around 7 hours to bring the temp back up only to loose it again that night. i am changing over soon to 2 200w eheims my advise to you would be not to buy the fluval e

I run a fluval e series (300w) on my rio 400 (400ltrs+) and also find it cannot maintain the temperature on its own, particularly thru the winter when the temperature drops overnight. So I added a another 300W (visitherm) heater at the other end, and now the temperature remains completely stable.

I always think its better to run two heaters, particuarly on a large volumne tank, one in case power fails on the heater and two, running together, actually old a more stable temp and are on less than running a single heater, which needs to be on full power constantly to maintain the temperature.
