casey05 Posted December 7, 2005 Report Share Posted December 7, 2005 im getting a new fish tank on saturday and i think its about 150L and i was wondering if a fluval tronic 150W heater will do the trick.Im just confused because some people have two in their tanks. :oops: Quote Link to comment Share on other sites More sharing options...
Wok Posted December 7, 2005 Report Share Posted December 7, 2005 yes that will be fine. what you need is at least 1w per litre of water. Quote Link to comment Share on other sites More sharing options...
monaro1 Posted December 7, 2005 Report Share Posted December 7, 2005 for a 150 tank a 150watt is good,normally 1 watt 1 lt if you have large tanks you need more than 1 heater Quote Link to comment Share on other sites More sharing options...
casey05 Posted December 7, 2005 Author Report Share Posted December 7, 2005 cool,thanks guys it was just that i saw a 165L tank with two heaters so i got a little worried in thinking that i would have to buy another heater too Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted December 7, 2005 Report Share Posted December 7, 2005 Some people like to have two for safety reasons, but when they fail they usually fail on and cook everything anyway. Quote Link to comment Share on other sites More sharing options...

Warren Posted December 7, 2005 Report Share Posted December 7, 2005 It's usually best to get the minimum sized heater you can get away with. I use 2 x 300W heaters on a 1200L tank. One is set to 27'C and the other to 25.5'C. The 25.5'C one almost never comes on even in winter but the other one is usually on nearly all the time. This means if a heater fails to the more common on-mode there is less risk of your tank getting 'cooked' before you notice. If you then use two heaters of the minimum size you cover both ends, tank won't cook as badly as one big heater if it fails on and the tank won't get too cold if one fails to the off state. For 150L in a fairly well insulated house you should easily get away with 2 x 50W heaters. Quote Link to comment Share on other sites More sharing options...
casey05 Posted December 7, 2005 Author Report Share Posted December 7, 2005 thanks warren .so i should get another and set it on a slightly lower temperature just to be on the safer side of things?that sounds like a sensible idea! :Dthanks again for that.
