Hi was thinking of getting 2 fluval 200watt E series heaters for my 240l tank,would this be overkill?was thinking that if there bigger they wont have to be on as long as the 100watt ones which are recommended for a tank size of 120l. Was going to have them both running and one acting as a back up heater just in case one failed.any advice much appreciated. Also anyone got one of these and how good are they, has quite a bit of positive feedback on the net.

Do it

personally i would have a fuval one as the main one and have another one as a backup, like an aquaone heater set at about 3 degrees lower than the fuval.

i dont see the point buying 2 good quality heaters when only 1 is needed and a cheeper one will do the same job as a backup.

can i ask what will be in the tank?

you can never go wrong with having two quality heaters, i would go for the jager though

which ever brand you choose, either fluval or jager they will last longer than cheap ones & do a better job.

actually, i put a 300W jager in a 300L tank. that works perfectly, flag getting two & get one big one.

thanks for the advice guys. its just a planted discus tank but had a heater fail one me, but lucky i caught it on time,was the only heater in the tank, so trying to prevent it happening again.

i would go for two 200 watt heaters if your set on getting two, not sure about the fluval but the jagers have a 3 year warranty.

Nice idea on getting 2 heaters. I'm sure you've spends hundreds if not thousands of dollars on your fish tank, why risk it all for another $50?

Works well, I have 2 300 watt heaters in my 450 litre tank, one set two degrees lower than the other and occasions they do both come on together. Its also a great backstop if one fails. If you can afford quality go for it and get two otherwise get one really good one and a cheaper one as the back stop. I find that the jagar heaters run for ever, not sure about the fluval though.
