I've read all sorts that 1 heater is better than 2 and vice versa, and various things on wattage to.
So my question to you experienced fish keepers is simple, what size, brand and number of heaters should i get?
The general rule for heaters is 1watt per litre. In your case your would need a 300w. If you minus the gravel and décor, you probably come in below 200ltrs, so you could get away with a 200w but a little bigger is better. Especially with the weather we get on this side of the pond. Some people like to have 2 heaters(eg 2x150w), so if one breaks they have something to maintain the temp until they get another. I just go with one large one as I have plenty of spares laying around. I personally love the Fluval E series heaters. Very good brand name, very reliable, very advanced and they look good too. I use the 300w in my 200ltr. If I went with the 200w, they tend to come on more often and with our weather, it would be on constantly...haha. Here's a video about them.....
