Just wondering... on setting up new heaters

[daniella3d]

On personal experience with my own corals. When temperature get that high I see retracted polyps and RTN follow if I keep it that way.

Stressing most animals at 77 F? Some of my stressed corals grow 1" per month. I have quite a few deep water acroporas now, and they don't seem to like hot water at all.

Maybe it depends on the species.

It's funny because you mention one reference, then others will say other things. Temperature is one of the most controversial subject it seem. I keep reading conflicting opinions. I know 82F does not work with my own reef. I put a fan so that when the temp reach 78 it start automatically. I never had RTN since I keep my temperature on the lower side.

If anyone is using this high temperature and it work for them and they never get RTN, then they should surely keep at it. Does not work for me.

The commonly advised mini-reef temperatures of 74 to 77 degrees Fahrenheit (22 to 25 degrees Celsius) are stressing most of the animals unnecessarily and, in some cases, severely."

In addition to this natural reefs fluctuate in temperature throughout the day depending on current. Observations between 76-83 are very common, what are you basing your statement on?

Although this info is very valuable to many reefers ...

The OP was only looking for advice on setting up new Eheim heaters

Let's stay on topic ...
