Ehhh you'll probably hear people on both sides of this fence. On one side, two heaters of the same wattage. It one heater dies, the other is large enough to support the tank alone. However if that heater fails in the on position, it might cook the tank. On the other side of the fence, two smaller heaters. Vice versa. I'd probably sit on the center of the fence just to be safe. Example: rather than one 300W heater, I'd use two 200W.Is it wise to use two heaters at the same wattage or split the wattage between two heaters?
Thanks for all the advice from everyone so far ! it is appreciated . My main reason the apex jr is price but mainly i thought it was a contoller for a failsafe to protect your tank from overheating wasnt aware the apex could be used to control heater temp ! i just thought it was if your tank got too hot it would shut it off !
yes lol is right !Yeah the switch inputs for the ATO was one thing I didn't think about when I purchased the Reef Keeper. I bought it for other reasons. But it is so friggin nice. I used to have an external relay box to control the float switches/top off pump. Now it's all done through the ReefKeeper AND has an emergency shutoff timer in case a float switch sticks or something.
And having a display for everything is very useful. Just by walking past the tank, I can glance at tank temp/pH/etc. I think I'd be more likely to catch a problem with the number starring me in the face all the time on a display. OH! And you can set up alarms, both audible and visual. So if something happens, it will alert you. "HEY!!!! GTF OVER HERE! THE TANK IS OVERHEATING!!!"
lol
interesting diy project for a controller
Finally got a chance to read through that thread. day trippr sure is an oblivious arrogant ahole. LOL I actually have a homebrew account and wanted to post that in there, but no reason to bump an old thread with pot stirring.For my freshwater tanks at home, I am using a basic digital temperature controller wired to an outlet in an electrical box. Something like this: http://www.homebrewtalk.com/showthread.php?t=337318#post4196885
If you wanted to have both heating and cooling capabilities you would need to get a STC-1000 and possibly wire it to two outlets, one for heating and one for cooling. The cheapest units are under $20 (mine cost $15), but one thing to be aware of is that if you go for the cheapest ones, the unit can only handle 5 amps. You can get stronger ones but of course they cost more.
The ones I am currently using had a total cost of ~$40, which includes wire, electrical box, outlet, and cover. If you opt for a GFCI outlet (I did), the cost will be a little higher.
Are you just using one heater ?
