I have a 3ft tank which is appox. 200litres, I have in it 2 heaters as I have not got round to getting a bigger one yet the temperature is currently sitting at 27C which from previous experience I have learned is about right, In the tank we have a Fluval U4 but I think we may need a bigger one or even another one at other side of the tank? Any advice would be much appreciated.
Thanks
