Hi folks,new to the site and this is my first post. I set up a Juwel Rio 240 last weekend and began a fishless cycle on Sunday.I have read on the forums here that it is best to do the cycle at a high temperature(mid eighties),consequently I set the thermostat on my heater to its highest setting of 32 degrees but my water temp.is struggling to get above 26deg. My tank has a single 200watt heater.Is my heater faulty or do I need to buy another one to get my temp.higher.
