Temp and Color???

[dahenley]

Hello,

Im a college student, with too big of a tank. (too big for my budget, but too small for my wants! lol)

I ahve always had a high temperature in my tank, but i contribute it to my 3-400W MH's and VHO Actinics, with a tall canopy, and fan circulation. (plus, my tank is against my back wall, so there is no ventilation of my sump that way either.

My tank over the summer here in Texas, has maintained about 85deg with my canopy doors open. but here recently, i have noticed myself closing the doors, and forgetting to re-open them.
I noticed a few of my SPS corals have started to die/skin fall off branches. and i checked my water temperature, and it was aboce 86+ (the temp was climbing and i quit looking)

SO, i opened the canopy doors, and placed a large box fan for ventiliation.
now, the temperatures are never above 79. (never below 76:bounce1

I have a few LPS in my tank as well, and i noticed that they are more fluffy and have better color as well. My SPS look to have better polyp extension, and i noticed some color change on some tipps of SPS.

Has anyone noticed a difference in the color of their Corals with the different temperatures of their tank?
I was just wondering.
Thanks

I have. I used to not monitor temperatures and of course they were swinging all over. The heaters I was using had horrible thermostats and as a result my temps would swing drastically. Now I use Ehiem's Jager heaters and my temps hardly vary from 77 degrees.
For me running in the 77-79 range has yielded the best coloration and growth of corals and the least algal growth.

Interesting. So the enclosed sump was contributing to a lot of the heat? Does the fan blow where water is evaporating, in turn, cooling down the tank? I'm looking for a cooling solution. Any help would be great.

Does a larger the sump play a huge factor in stability?

Many people get away with having a opened back stand, and using a clip on fan or some sort of vent to blow across the sump. this causes evaporative cooling. (one of the most energy efficient and cheapest of cooling options.)
My stand is against a wall with no space, which doesnt allow me to have any ventilation down there.
a large sump is nice if you can use a fan to cool it. then yes, good choice.

The picture above is my solution for now. its a box fan blowing across the main tank. it works great, but it looks like POO.
