Deno Posted August 24, 2008 Report Share Posted August 24, 2008 a 200w heater does 200L so can i assume that one at each end will do a 400L tank? Quote Link to comment Share on other sites More sharing options...

whetu Posted August 24, 2008 Report Share Posted August 24, 2008 Yes, basically that is correct. In general I prefer two small heaters over one large one, so if one heater gets stuck 'on' or 'off' you have more time to react before too much harm is done. There are a few things to consider with heaters, for example if the room the tank is in gets particularly cold in winter (e.g. overnight) you're likely to need more total wattage. If the ambient temperature of the room is always warm (e.g. if you have some kind of central heating) then you can get away with less heating in the tank. Also of course it depends on what kind of fish you're keeping and their preferred temperature range. To keep a large tank in the high 20s is obviously going to need more wattage than keeping it in the low 20s. Make sure the heaters are positioned in an area with good water circulation so they keep the tank evenly heated. So yes, 2 x 200 watt heaters, one at each end of your tank, sounds good.
