Regrettably, the quick overview is incorrect. This heater should not be mounted in any position other than vertically, with the cord and buttons at the top. We will get that updated ASAP. Have a great day.
Heaters are one item that I would not recommend going higher than what you need. If the thermostat were to fail in the on state and you had a larger one in the tank it would cause problems faster. I would stick with the 75 watt recommendation.
If you have any other questions please let us know!
Have a great day!
We expect around 1.6 amps. Feel free to let us know if you have any further questions!
Is the 25Watt Neo-Therm ok for me to use in my tank?
I would like to set it about 78 and hold it there.
My last heater rose the water to almost 88. Not good.
Typically 2.5-5 watts per gallon are recommended. While the 25 watt could work if left on the lowest setting and certainly can work well with safety built in it has the potential to over heat if left on too warm of a setting.
What kind of cobalt heater do I need, how many watts
You will want 2 of the 200 watt heaters for good coverage of your tank! Feel free to let us know if you have any further questions!
The heater should remember the tem, but that said with a setup like this what you would want to do is set your heater for your desired temp (say 78 degrees) and then set your Apex as an emergency cutoff to cut the power if the temp gets too hot and it appears the heater has failed (say 79.5 degrees). That way the heater is in primary control and you will avoid constantly cutting power to and from it (which may be hard on the heater).
There isn't a calculator as each heater is a bit different, but all of the manufacturers do have recomended size aquariums for their heaters. If you look at the full details of this page there is a quick comparison chart to help you match the heater size to how big your aquarium is.
Thats not a problem at all. If the heater is larger it just won't run for as long, nothing to worry about!
It won't shut itself off (I don't know of any heater that would). You will want to unplug it before its removed from water (or if you have an aquarium controller you setup something like a feed mode to shut down your pumps, heaters, etc at the press of a button for when you do a water change).
I think they should be here this week :-) The different outlets have different amperage allotments but in general unless you are using two very large heaters your not going to run into any issues :-) Just for example, the 8amp outlet would be able to power about a total of 950watts. Should be way more then plenty for a 55g tank!
Most of us around here use the Neo-therm but the second most popular has to be the finnex HMO series heaters. Assuming you don't have an aquarium controller yet I would get something that has a digital thermostat as they are a lot less likely to fail (in particular in the ON position).
