I was wondering if anyone here who is familiar with the Hydor 25W Submersible heater can give me some help (this is the heater: http://www.amazon.com/Hydor-25W-Subm...pr_product_top
1. When it's on and working, does it feel warm to the touch?
2. How long did it take for it to start heating the tank (a few hours?)?
3. Do you have any tips on how to get it to work?
This is my second heater in a row that is not working. The first one was a cheapo one from Pet Co. that kept the water at 70 degrees. A few people here suggested I try the Hydor 25W heater, and I read the great reviews on amazon, so I decided this would be the right heater. But it doesn't seem to do anything. The light comes on indicating that it's working. It's set at 79 degrees. But the water in my tank is 70. When it's on and I touch it, it doesn't feel warm at all. I'm having the same problem as I had with the cheapo heater. I have it in a 5 gallon tank and it says it works in tanks up to 7 gallons, and a few reviewers even say it's working in their ten gallon tanks.
I am so frustrated! My poor fish is dealing with too many temperature changes! I don't want to buy yet a third heater. I'm wondering if somehow I'm doing something wrong. The heater sat in this tank for days before I plugged it in, so one would think the thermometer inside the heater would be adjusted to the water temperature just fine. Any advice?
