Answer:	Dear Jordan woodruff, the length of the wire from the heater to the controller is 63in, and the total length is 95in. I hope my answer can help you.
Question:	Can this heat a 300 gallon pond
Answer:	Hello, the aquarium heater is recommended for indoor use only. We mainly consider from the following two aspects. First, the use of heaters outdoors is greatly affected by changes in ambient temperature, because the outdoor temperature may be below zero and the heating effect is not ideal, and the number of heaters used will be more than indoors. Second, the safety of electricity during use, if it is installed by non-professionals, leakage problems may occur. I hope you will consider our suggestions carefully. In addition, please pay attention to the installation method, and do not insert the heater in the mud; in the process of using the heater, in order to make the temperature of the fish pond even, be sure to use it in conjunction with the circulating water pump. Hope my answer can help you, thank you for your question.
Question:	how long will it take to heat 160 gallons starting from 50 degrees
Answer:	Hi Radfischer, the heating time is not only related to fish tank capacity and heater wattage, but also related to ambient temperature and water circulation. Assuming that the ambient temperature is 50 degrees Fahrenheit, using our 1200w heater to heat from 50 degrees Fahrenheit to 82 degrees Fahrenheit, it takes about 8-13 hours according to our experiment.

User questions & answers

Question:	Do I need to use a heater protector to prevent my musk turtle hatchling from burning herself? Has anyone found a good-fitting protector for it
Answer:	This heater MUST be submerged in water. If your turtle is basically a land reptile, this one won't work as a space heater. There are some other ones out there for that purpose.
Question:	Has anyone calculated yearly cost of operation for a 20 gal tank in a 50 degree room? Estimates
Answer:	It would be difficult to calculate an exact cost with so many variables. Is your 20 gal long or tall or hex? Does it get any sun? Is it live planted? What temp do you want it at? What's in it? What filters do you have and what is your gpm turnover rate? To get your answer: Tank volume ÷ sq inches of tank = A. A × gpm rate =B. (If live planted: add A + B =C. C ÷ 15.275 = D. Subtract C - D = E. If not B = E.) From here take average water temp × E = F Multiply F × 8760 (hours in a year) = G. This is your hourly. G × kph rate of your electricity = H. And finally you will take H and multiply it by; Why in the hell do you want to be in a 50° room? Better yet, why would you want to keep fish in there??
Question:	I’ve had my heater a few months now and noticed a brittle film peeling off the quartz part of the heater. Should I be concerned
Answer:	Oh, have it been bumped? Could you contact with us and give us a photo? This heaters have been manufactured and sell to all around the word for more than 10 years, but we never heard this situation.
Question:	Will this work well in my 40 gallon red eared slider tank
Answer:	We use it in our 60 gallon for our red eared and it works great. Have no problems. I truly think it is the best heater we have gotten. You can maintain the temp in the tank very easily.
