Peter, outstanding tank room, reminds me of a public aquarium installation, only nicer!
btw, I noticed that liveaquaria.com lists almost all their corals and reef fish at 72-78 deg F optimal temperature, I have sent them Ron Shimek's article and asked for their response, I'll post it here, I still don't understand why everyone keeps their tanks at cooler temperatures, I wonder if it's due to our closed systems and the consequential variables at play

I posted this temperature issue on another forum and someone posted this reference from Randy Holmes-Farley:
http://reefkeeping.com/issues/2004-05/rhf/index.php his comments on temperature are: "Temperature impacts reef aquarium inhabitants in a variety of ways. First and foremost, the animals' metabolic rates rise as temperature rises. They may consequently use more oxygen, carbon dioxide, nutrients, calcium and alkalinity at higher temperatures. This higher metabolic rate can also increase both their growth rate and waste production at higher temperatures. Another important impact of temperature is on the chemical aspects of the aquarium. The solubility of dissolved gases such as oxygen and carbon dioxide, for example, changes with temperature. Oxygen, in particular, can be a concern because it is less soluble at higher temperature. So what does this imply for aquarists? In most instances, trying to match the natural environment in a reef aquarium is a worthy goal. Temperature may, however, be a parameter that requires accounting for the practical considerations of a small closed system. Looking to the ocean as a guide for setting temperatures in reef aquaria may present complications, because corals grow in such a wide range of temperatures. Nevertheless, Ron Shimek has shown in a previous article that the greatest variety of corals are found in water whose average temperature is about 83-86° F. Reef aquaria do, however, have limitations that may make their optimal temperature somewhat lower. During normal functioning of a reef aquarium, the oxygen level and the metabolic rate of the aquarium inhabitants are not often important issues. During a crisis such as a power failure, however, the dissolved oxygen can be rapidly used up. Lower temperatures not only allow a higher oxygen level before an emergency, but will also slow the consumption of that oxygen by slowing the metabolism of the aquarium's inhabitants. The production of ammonia as organisms begin to die may also be slower at lower temperatures. For reasons such as this, one may choose to strike a practical balance between temperatures that are too high (even if corals normally thrive in the ocean at those temperatures), and those that are too low. Although average reef temperatures in maximal diversity areas (i.e. coral triangle centered Indonesia,) these areas are also often subject to significant mixing. In fact, the cooler reefs, ( i..e. open Pacific reefs) are often more stable at lower temperatures due to oceanic exchange but are less tolerant to bleaching and other temperature related perturbations. All things considered, those natural guidelines leave a fairly wide range of acceptable temperatures. I keep my aquarium at about 80-81° F year-round. I am actually more inclined to keep the aquarium cooler in the summer, when a power failure would most likely warm the aquarium, and higher in winter, when a power failure would most likely cool it. All things considered, I recommend temperatures in the range of 76-83° F unless there is a very clear reason to keep it outside that range."

Fantastic mechanical detail!
What a fish room!!!!

The View
This is the view out from the picture window in the fish room.........
this is the electrical switch panel at night with no devices drawing any current. |

Various Controllers
This arrangement works so that the thermostat for cooling works from the remote. That means I can move the remote around the fish room to an ideal location if there is a hot spot. The humidity sensor for the HRV is located reasonably close to the air flow from the tank canopy into the fish room.
controller for the second chiller..........closed loop system B controller for 'Robbie the Robot' (skimmer) followed by the control for Robbies bubbles........... temp probe and controller for the first chiller, closed loop system A in the bottom middle of the frame.........the probe sits in the refugium which is the last stop before re-entry into the Display tank.

EYE Candy
This is the tank at night.........without water of course
This is the tank in the morning........I call it "fish tank in a spring morning" This fish motif is in all the wrought iron work.......its sort of like a fish jumping out of the reeds..........but my fish will be well behaved and stay in the tank where they will be happy!!!!!! Wine Closet Peter |

And now some homework for the experts........
I have a question........My second chiller came with a slightly different pump with a small barrel canister filter /that the first one didn't have. I just realized that the tall canister filter sits after the pump but before the UV and the chiller. My question is................why isn't there a filter canister in front of the pump to protect it from the likely event of sand and gravel coming from the display tank.
This first closed loop (system A) does NOT have a prefilter canister in front of the pump. I hope that made sense. Comments???? |

I don't run any filters before pumps or chiller and have never had a problem

That is what I refer to as a leaf basket, they really don't trap much. (seeing as i'm always cleaning sand out of the impeller of our pool pumps at work)
I did however have one question Peter. WHERE is the wine? You cant taste wine if there is none. (this is one of my favorites) http://www.jimbarry.com/wines/detail...PrdctsTheMcRae |

The Leaf-Basket as N-dog stated, can be used to trap large particles before they get to harm the impeller,(leafs, snails, etc.)
It also (mainly) is used to Prime the pump in a suction feed setup.... suction draw, where the pump is higher then the water level, you place a check valve on the suction pipe, (usually below the level of the pump) fill up the Leaf-basket with water, screw on the cover, and start the pump, primed!

I like the logic in the paper you referred in your other post. The range appears to take into account a number of considerations raised by Mr. Wilson et al with the risks associated with the extremes. Given the feedback we have had here so far I wonder if there is a material difference when considering the size of tanks. Lets say that tanks over 1000 gal may have a support environment different than say tanks under 300 gal that would affect the ideal target range. It would appear that users who have very large tanks also prefer the lower range and I would bet that other elements such as oxygen and even ozone which would likely be a prevailing affect with the technology found more in use with larger environments. I would like to believe that the talent sitting on this thread could or at least should be able to arrive at a consensus that would be helpful to anyone using Mr. Wilson's book as a guide to support. Somehow I believe Mr. Wilson will have additional comments that will help us in this regard. Peter so far I believe that the discussion on this thread on this subject would have me establish a target of 78-80 F for our tank..........I think. |

I realize that the coral landscape around Australia provides for a huge varience in temperature ranges, often times in the same location!!!! However as you know there are certain places where the coral varieties and speices are as good as it gets. So one question you might answer for us is what is the temperature range in your all time favourite diving location where the corals in the wild are at their best? Peter |
