View Full Version : What temperature do you keep your SPS and LPS reef tanks at?

I just changed my pump from a small internal return to a large Iwaki 100-RLT which is a 1/3 horsepower and kicks 2,000 gph at 17 feet. I noticed that my temp increased from 78' to 80.5' now after changing the pump. We also changed some other things, so it may not be the pump. But I would like to know what you guys keep your reef tanks temperature at, and if you have ever increased your tanks temperatue by changing a pump. Thanks again all!

Mine is usually from 79 - 81 in the winter and has gotten up to 83 - 84 on occation in the summer.

78-80 winter. 80-83 summer.

Pumps do produce heat and may alter temp.

Thanks guys, keep them coming. What fish is that MR_O98 as that is AMAZING?

I think it's a peppermint angel.:D Actually I wouldn't have probably known that, had I not just read it in this thread a few minutes ago!:lol: Check out page 3, and you will see a bigger picture of them.

79-80 F degrees. Yes, it is a peppermint angel.

Keep them coming as I want to know if 81-82 is going to be too hot and if so, I would buy a chiller. Thanks!

Mine varies from 77-83 depending upon the time of the year. 81-82 should be fine.

Mine runs 76-80 and when it hits 80 I get stressed out. I like to run a cooler tank, my sps don't grow as fast as some in the hotter tanks, but my inverts look happier and I have very little problems with disease or excess algae, despite having a poorly skimmed and heavily stocked tank. I noticed at 80 and above I had shrimp dropping like flies.

79-82. The reefs typically see 4-5 degree swings on a daily basis. There is a body of research suggesting corals that grow in areas with higher temp swings are better able to withstand temp spikes. Same coral in more stable area bleaches faster. I have no problems with inverts. There have been some good threads on this 2-3 months ago.

up to 84deg during the summer and always between 80-84. never a problem.

right now with no chiller im 75 night and 76 day(lights on)

sorry double

77 - 81. I swing about 3 to degrees per day. I have fans blowing across the surface 24/7. The only time they are off is if we are expecting cold weather. my goal is to never go below 77 and above 82.

I shoot for 78-79. It sometime wonders down into the 77 range or up to 80 range, but i try to keep it from swinging more than 2-2.5 degrees in a day.

78-84 depending on the month.

it should be constant at 76-79 (under 80) Most places where the corals come from aren't above 80.
