simplydiscus.com link isn't working this morning for me. I'll try when I get home and send it on. I was there last night so I know it's good. Simplydiscus is the more active of the two and I "think" that it was where I saw the heater info.
wow it's been so long, from this thread i ended up with Ebo-Jagers just cuz they're tried and true. You're timing couldn't be more perfect though as i'm going to need 3 more heaters of 200W or higher. Now, which titanium heater do you recommend? I'm going to look it up on www.bigalsonline.com
I've been using the Won-Pro titanium. When you buy titanium heater, you can use less wattage on the same amount of WPG. Here's some loose guidelines:
0-10 Gallon Tank - 50 watts
10-40 Gallon Tank - 100 watts
40-150 Gallon Tank - 200 watts
150-250 Gallon Tank - 300 watts
Over 250 Gallon Tank - 350 watts
The next heater that I wants to try is the Hydor External Heater.
Not to stray off-topic too far, but Texas' post has spurned a question in my little brain <spoken in the tone of Tweetiebird>.
Barring no mechanical failures, are there dangers associated with 'over-powering' a tank (ie. using a 300 watt heater on a 30 gallon tank). I ask because one of my tanks is in a very cold room, and frequently shows temp swings. The old 5 watts/gal rule seems to break down with very large and small tanks (probably the result of an exponent - like most other aquarium 'curves' ).
A possible problem I could see is that the water in the proximity of the heater gets warm quickly, and causes the heater to turn off too early. Some heaters, like the Via Aqua Titanium Tubes, have a separate temperature sensor, which you can put a little further away from the heater, thus resolving that problem.
The 5 Watt per gallon rule is more for a "regular" heated room, in very cold rooms you might need more indeed.
Yes, acrylic wil hold heat better then glass. I have a leftover 300Watts Won-Pro and I put it in my 55G. No problem so far. The external dial on the Won-Pro is very easy to turn. I would tape over the dial after I'm done with the temp setting. That way I don't boil the tank if the temp dial is accidently moved.
one thing about the ebo jager heaters that i noticed is that they don't follow the 5 watt per gallon rule of heaters.... for example, they say their 150Watt is good for tanks from 40 gallons to 60 gallons!!
but i like to hear what yall know about this from experience.
