Tank Temp

[duc]

I'd run them constantly for a while until it's somehwere near where you want it. 66 CFm isn't going to drop a 150+ gallons while you watch it. But you don't want a large fast swign either. Overnight tonight might get it where you are comfortable. Then I'd try running them just when the lights are on. Plug into the same light timer if you use one. You're on the right track.

Thanks I am all over it Last night I ran them all night and forgot my heater wasn't plugged in any more, well this morning my temp was 74ish from last nights 80ish. Heater is on an so are the light, hopefully that was the only huge swing in temp I will have and hopefully everyone in the tank just thinks an overnight cold front blew through.

im keeping my reef at 86 constantly cause i cant lower it anymore and nothing is bleaching plan at add some fans to lower temp though

86 is really pushing the upper limits of what the corals will handle. As I said earlier I have had a lot of problems with Ich on my fish when the temp gets up that high because you are stressing them.

Remember that the solubility of oxygen goes down as temp. goes up. You can get to a point where you may start to oxygen deprive your fish.

Today I lost 2 gallons of water and my temp stayed between 78-80 so woohoo I have beat the mighty heat gods! I moved my fan power to my light timer and I will let my sump heater deal with the lower temp. I guess if it gets to warm as summer progresses I will move them to there own timer.

86 is dangerously high for most corals we keep.

Perfect! Good job. The key is to try to use your fans and a heater to minimize the temp swings between day and night time.

I use mine on a controller. It works great.
