advice for New heater
Need advice for my 180litre tank the thermostat I had in was a 200 for my jewel Rio but the temp at night was dropping really low so I went out & bought a new one which is a jewel 300 but the temp is dropping at night still, it goes from 27 during the day to 25 at night. Does anyone else have this problem? Is it ok for my fish. Thanks any feedback would be appreciated.
