Well i just checked my temp and i've had the fan on the sump for a couple hours and it's come down to 81.9 from 82.4 so im gonna keep an eye on it and see what it settles at during the day and night after i give it a few days if it's still above 78 i'll slowly start bringing on my MH's and unplug the heater. I dont want it to drop 5 degrees in one night

where do you check the temp at in the tank or in the sump. you could be getting some heat from the lights. i suggest checking deep in the tank or check in the sump. or are you using one of those strips that stick to the tank.

I have a probe that i suction 4 or so inches from the top of the display tank. But i wouldn't think i would be picking up much if any heat if im just running T5's which are hanging more than 12 inches from the tank.

If you have good circulation the temperature should be nearly the same every where in your tank and sump except the very thin skin of water at the surface of your tank and sump top surface which will be a very little bit cooler due to the evaporation cooling effects. With adequate tank circulation the temperature of your sump water will match your tank water. All parameters for all parts of a tanks system should always basically be the same. There will be exceopptions to the rule like a higher dissolved oxygen levl near the exit of a skimmer or in a refugium with macroalgae when the fuge light is on, but with good circulation even these should be diificult to detect. It would be easier to make good suggestions about your heating problems if more dat was available. Fot instance what is your normal room temperature. How much water are you loosing to evaporation every day. With 72 gallon tank it would be nice to shoot for 2 gallons per day of evaporation with fans running only while the lights are on , as you wabnt the evaporation to happen only when you want to drop the tanks temperature. Water evaporation removes huge amounts of heat energy from water bodies (IE your tank). Fans increase the evaporation by moving the moisture laden air out of the way and bringing in replacement air that is drier so that it can pick up moisture to carry away. If you live in a drier climate it works better than if you live in a humid climate. It works very well in the dry southwestern part of the United States. The fans basically turn your sump into a "swamp cooler."

I noticed this thing growing in my tank last night. I guess It's some type of scallop.

I got 2 Acropora frags today at my LFS if they do well i plan on getting a Tortuosa "Blue Torte" in a few months.

Those look very nice. Congrats!

Thanks biff

my camera does some strange lighting when I take pics with my halides on, so my tank much brighter than it looks. I got my 14k MH a few days ago to replace my 10k bulbs, im much happier with the 14k.

I just ordered new bulbs for my halides also. So far, I've used 10K, but the new bulbs I ordered are 14K. I'm pretty sure I will like them better too.
