Are we to assume that you have verified that the temperature reading is correct?
What is the room temperature? If over 78, can it be cooled down a little?

We live in Utah where humidity is low enough (20-40%) to make evaporation a smart way to cool things. A small clip-on fan can be placed to blow across the water. By adjusting the angle of the fan across the water and adjusting the speed of the air flow we can drop the aquarium temperature anywhere from 1 - 15 degrees. So much better than a chiller for so many reasons.

I just picked up a nice new small chrome fan at the DI for $2. I wondered why I felt like buying it. It must be for you. Smile

I found this pic of the top area of a red sea max s 500 Is this the space between the lights and the water? There isn't a glass or plastic cover over the top, is there?

Those $8 clip on fans from Walmart work really well.  In my 120, it would drop the temp of the system down 1.5 degrees.

I looked on their website. It also appears to have 3-4 submersible power heads with the return pump. They also have a designated spot in the stand for a chiller so they must know of a heat problem.

Mark - My tank is just like the picture you posted. Nothing between the lights and the top of the water. My brand new digital thermometer is reading 82.9 degrees with the lights on. The room temperature that the tank is in is 70 degrees too.

You can buy anytime of clip on fan and point it right at your sump water, that should help cool it down a bit

Brand new digital thermometers can still be inaccurate. I would double check it with ice water. It won't take but a minute to check.

If you are running that hot, get the temp down! A cheapo fan will do just fine!

I totally agree. Digital thermometers need to be checked for accuracy!

I'm a little surprised that this thread is going as slow as it is. This problem is urgent. Why not call me now to get your questions answered and get the problem solved immediately? My number is 808-345-1049. Call right now. I'm serious.

Shocked Something is very wrong. The tank should not be that hot in a 70 degree room. Call me now so I can help you get to the bottom of this problem. I've helped hundreds of hobbyists that have made that call.

If it does have four submersible pumps along with the main pump that may be where all the heat is coming from. I added a uv to my tank and the extra pump was taking my water from 76-77 up to 80 degrees so I had to turn it off during the day time when lights and what not are running. Especially with your lights being as close to the water as it looks like in that stock picture

I agree with Jackie. Chances are the room is getting warmer than 70 degrees. I haven't read most of the other comments but I imagine you've got your heater(s) dialed way back or unplugged?

I've checked my digital thermometer and it's spot on. I've decided to run just six T5s, instead of the 10 T5s. It seems to help keep the tank temperature to 81 with lights on and 79 with lights off. Thank you everyone for your input!

That's not much difference from what it was with 10 lights. My coral would not be comfortable at the temperatures you are talking about. And from what you said over the phone, the temp does not drop much at night, probably because of the 6 pumps! I would work to get the temperature lower, especially with warm weather coming on. At those temps you must be losing a lot of water to evaporation already. I'd find a way to run the RO water to an auto top off valve.

I saw one of these tanks at Petco the other day. It looks to me like the tank was ill designed with regard to temperature. For one thing, they should have made it so the lights could be raised higher.

Even with it's disadvantages, it could be DIY'd to overcome those disadvantages. It can be done. I would be happy to come by and take a look at it with you. Let me know.
