heat issues

Ahh...that's true - I think you get more sun than I do. I think my place clears up last in SF from the fog.

Turning a bulb on and off creates far more wear then simply running it. 2 years seems like a strech, even on for 4 hours. I run mine for 5 and I have to replace every year (as per PAR readings).

I guess I have been lucky, I dont have to replace them very often, plus with two bulbs running parallel, I dont notice PAR degration as much so am running mine longer ....

sfphysics, yeah I know what you mean sometime I think am saving energy but am actually not :D :D but it makes me feel better :D :D the japanese tanks are beautiful, I think sometime they take things to the extreme though.
 
Well, back to the subject.

When I thought I would have heat issues on my 120g I installed 4" fans that were to come on when the lights were on, as it turned out my tank doesn't get warm up easily.

The fans would definitely pull temp down considerably, but the top-off wasn't so hot as I had to top off an extra gallon or so of water just due to the fans alone.

Gresham: Really, hmm that's good to know, I thought it was a simple design where you'd simply hook up a thermal couple and it'd turn on/off depending upon the temp. I don't have a kiln so good thing I didn't buy one! :D

They have logic in them :( The curve, etc

Lucky for me I have an automation expert at my work, and I'm, friends with all the top RC automation experts :lol:
 
get a cheap basic aqua controller to control fans. its always helped with my tanks even running more than 1kw of power. never owned a chiller but then again, in dc we get hot weather like a few days out of the year..haha
 
Keep 5 gal or more of saltwater in a cool place like the garage or basement. When the temp gets too high, do a water change.
