2 Heaters Or 1

[mattlee]

i will be setting up my new tank at the weekend and was wondering after seeing previous posts etc if 1 x 300watt heater will be ok or would i be better with 2 x 150 or 200watt heaters one at either end?

i would say 2 because it spreads out the heat and if one dies the other is still running

What size tank is it?

 

[mattlee]

its a fluval roma 240, 4 foot, it came with 1 x 300watt heater

Two 150watt heaters then. That way if one fails or gets stuck on, your fish are less likely to boil/freeze. It may also pay to buy two different brand heaters.

any recomendations.... my lfs are selling renas at about £19 i think and fluval about the same. 1 of each?

More expensive but less risk of burning to fish:

I bought the 300w version. I'll be adding another when I eventually get my second filter.

would one of these work with a fluval external as they have large pipes....?

 

[Geoff1991]

You can get different versions of the heater with different size fittings. I have the 200w version and i cant fault it.

 

[jmkgreen]

The 200w has 12/16mm pipe connectors the 300w has 16/22mm pipe connectors so pick which one matches the tubes on your filter.

^ The 300w comes in two sizes but i think the 2nd is hard to find.

how about the rena heaters that attach to the intake pipe of the externals or fit inside tank.... are they anygood?

 

[Geoff1991]

I hear they are good but a bit bulky.

Also if waters being heated then going through the filter... Id say the water would cool down slightly..
