My aquarium Temp

I thought i would share this little bit of information about the temp in my aquarium.

 I realized that I was going to start having a tempature problem when I bought my 3 175w metal halides for my 125 gal aquarium so I started to look at chillers but then I was even more shocked at how much they cost. especially for something that I was hoping to not even need. But then I built a 55 gal refugium to replace the very tiny 29 gal refugium I made before. Ever since I made this switch I have knowticed that I no longer have a problem with my water temp. I guess for the large amount of water under the aquarium where it actually has time to cool off before it runs back into my tank actually keeps the water where it needs to be. right around 78.5 durring the day (AC stays at 75) so it actually works out great and saves me a few dollars. im not sure how well this will work for people with higher wats on there metal halides but its food for thought if your trying to save a little money.
