I live in Indiana and now that fall is upon us, I am again struggling with temp regulation for my tank. I was just wondering what others experience and what they have done to fix the problem. I was thinking of adding a second heater to the system.
If you can't keep the tank warm enough, then yeah... it implies not enough wattage. What size tank and how many watts of heater do you have in there now?
As others have said, yeah... 400W on a 65g should be no problem keeping things warm, even in a cold room.
You say you're "struggling with temp regulation"...
What exactly do you mean? Can you not keep it warm enough? Does it vary too much? Just not sure what we're trying to fix...
How are you measuring the temperature of the water to know you have a problem?
