"hot time summer in the city"
I think it is safe to same that the norm temp for running our tanks is 78-80. I am debating with an experienced vetran on another sight who insists he runs his tank at 90 degrees plus with no problems because that is what it gets to on real reefs.
Here is what I have initially stated: True, for tropic regions---but that's open sea--not a closed ecosystem like our tanks. We have to expose corals to that high temp that might not experience it in deep water---the surface area might be that high but not at a lower depth--down there it is constant and cooler--so sometimes we are forcing corals and fish to adapt--something they don't do well. Also the higher temp 'creates a possible situation" to alter water chemistry allowing for increased DOC and carbon dioxide levels. It also wears down fish immunity in some fish trying desperately to defy nature and adapt to higher temps--leaving them open to become infected with organisms like ich. help me out here--I don't think I am way off base here--but I am I am completely open to correction __________________

I had my temp spike last month up to 94* and it didn't look good. I lost a couple fish and several corals. I'd say 85* is the absolute max.

Ouch! 94 is quite high. Are you thinking of getting a chiller for your tank?

I believe chillers are the best investment and getting cheaper for a saltwater tank.
Alot of LFS also allow to by over a 10 month interest free period which helps to get the purchase past the other half. |

For the most part the guy you're debating with is right. 90 is a bit high and is in the danger zone for most species though. Some reefs do get that high (i.e. Kwajalein, one of the world's biggest atolls), but most only average a high of about 86.

Do you not feel that we should be conservative with our temp in reef tanks--80 degress or so---to take into the fact that most of our reefs are a mixed bag of creatures from so many differing areas in the world?

that is good to hear. When I went home on my lunch my tank was 83.5 and I freaked out. I checked both heaters and put some frozen bottles in the sump until it got to 82.5. My house was 78 so I have no idea why it got so high?? I guess I will have to watch that in the future.

if your temp goes up and the house is cool... check the heater. mine was running even though the temp in the tank was 83 and the house was 78. i have learned that quite a few of the heater elements/thermostats can be faulty or poorly calibrated...

thanks greenbean---I assume that temp goes for inverts and fish also?

I have had the most problems with heaters then all other equipment, usually sticking on, but if you think about it they are constantly cycling, pumps are running constantly, and I have tried many brands of heaters, none have seemed to be better then the other. MH can add allot of heat and cause temp swings even when you have the AC on.

my next investment is in an aquacontroller for these reasons

Does this ability to adapt to sudden changes also apply to salinity,pH and alkalinity----and the big one ammonia/nitrates? Scott

I refuse to buy a heater!

As far as pH, the answer is pretty much the same. A range of about .4-.6 pH points from day to night is nothing to worry about. Alkalinity, I don't know about. I'm not sure anyone has quantified short-term changes. Nitrate and Ammonia are also a bit of a mystery. Like most parameters on the reef, they aren't stable. There are pulses of nutrients due to upwelling, internal waves, storm runoff, disturbed sediment, fish sleeping in coral heads etc. but whether those pulses help or hurt the reef is still being debated. There is work supporting both sides. Despite what you hear in the hobby and even in the mass media, the role or nutrient dynamics on reef health is very poorly understood.
