mY AC is set at 82 today, shouLd keep the taNk at 84 or beLow

... steamd fiShy anyoNE ?

I have a small window unit right by my tank too small for the room size, but good enough to keep my reef happy. Keep it on energy saver 77-78. I also have a chiller as a backup and to lower my temp swings. My tank has stayed 78-80 during our heat wave.

keeping in mind, it's not just the heat - the relative humidity has more to do with it than the actual temperature.

2 weeks ago we had an 83 degree day with high humidity and my tank hit 84

we are now at 97 and high humidity and I am rock solid with tank temp at 85 and animals no worse for the wear - a degree difference in tank temp but oooddles more (14 degrees) in actual outside temp.

on days like these I run a stand alone 10k btu ac set at 74 in the basement - the system closest to the AC solid at 78 other is at 82 today - we'll see when i get home.

be very careful with running your chiller. The exhaust heat from them can boost room temps making the chiller and ac work harder. Chillers might sound like a great idea but you need to know if it is worth it for your application. In a small room you might end up just burning electricity and heating up your tank.

^^^ a lot of people don't seem to realize this.

My concern with getting a chiller.

The last chiller I owned I had to place in a seperate room, that we rarely used, becuase it would make it so hot.
I run a 3 AC's now and they cool my entire Apartment to 70. My tank stays at 76 with the MH on.

	MH Metal Halide Lighting, typically used for high intensity light demanding corals such as SPS. Bulbs come in varieties of spectrums (7k, 10k,20k), and intensity (175W, 250W, 400W).

MIKE IS 100% right If the temp is getting to hot, even with the A/C running full blast, I would keep the MH lights off until the hot spell breaks. Either run you other lights, VHO, PC or T-5, or leave the tank dark for a couple of days. The tank will be fine without light for a couple of days

	MH Metal Halide Lighting, typically used for high intensity light demanding corals such as SPS. Bulbs come in varieties of spectrums (7k, 10k,20k), and intensity (175W, 250W, 400W).

	PC Power Compact Lighting, typically used in lower light aquariums supporting soft corals, LPS, and fish. Their low cost and cooler operating temperatures are an excellent choice for beginner aquariums and smaller tanks.

	VHO Very High Output Fluorescent Lighting - Fluorescent bulbs that run on special ballasts and have an output that is significantly higher than normal tubes. It is very possible to run an entire reef system on VHO lighting providing the proper number of bulbs and mixture of spectrums are chosen. For most hobbyists, these tubes are used in conjunction with Metal Halide lighting for simulating dawn and dusk. They often provide the "bluer" end of the light spectrum and thus a more aesthetically appealing display.

Does anyone know the limit of how high the tank temp can go without having negative effects? I've topped out at 82. Today I have been able to keep the tank at 80 but I had to keep freezing 1 qt containers and attaching to the side of my tank.

I keep my house at 72 and my tank at 79 this requires to run my AC 26000btu 18 hours of the day along with my 1/4 hp Chiller which runs at least 16 hours.But that keeps my reef happy and my family so its worth it.

Have my ac on full blast. However the temp of the tank did go up to 83. A fan brought it down back to 79.
I put fan right on the sump.

Quick question. I haven't done it but it's been an Idea in my head ever since the heatwave. What would happen if you made saltwater ice cubes and put it in the sump. ONLY if the tank went up to drastic levels?
