I am in the process of treating for ICH with higher temps and salt. My problem - temp does not hold. I have a Hydor Theo 200 watt heater that my lfs sold me when I got the 55 gal tank back in January. According to Dr Foster & Smith's website, that heater is good for 26-53 gal. Should I invest in another heater to supplement the one I have or get a higher wattage one to replace the 200 watt
