I always ran across differing opinions on floor support when it comes to our hobby. This was written by a structural engineer, but in what I feel, easy to understand language. Thought maybe someone might be interested...

One of the questions that is inevitably asked in every aquarium chat room, newsgroup and bulletin board is "just how large an aquarium can my floor support." Then the answers follow from people who usually use basically correct structural...
Purpose of Thread:
This is a brief description in "Laymans Terms" of how to feed and keep large polyp non-photosynthetic corals (NPS coral). I see countless threads and questions regarding "how to feed my new sun coral", or "how do I get the polyps on my new sun coral to open?" They're honestly a relatively easy coral to keep, some just require a little TLC. The following process can be followed for any large polyp non-photosynthetic coral Genus, such as Tubastrea ("Sun Coral")...
Depth of FIELD (or Focus)!!!!
Most simply stated depth of field is term used to describe how much or how little of your picture is in focus. There are several factors that determine the depth of field, but none is more profound then the aperture used to capture the image. A large aperture will result in LESS depth of field then a small one will. There are other factors as well, focal length, and the distance from the camera to the subject, but neither of these are as dramatic as...
Okay, this is my first photo how to thread in a while, so please bear with me.
Extension tubes are available in a variety of sizes for SLR cameras, there are 3rd party brands and there are ones made by the OEM, but they all have the same purpose, to reduce the minimum focus distance of a given lens. All of my examples are taken with the same camera, the same lens, and the same aperture, so that depth of field was not affected in that way. The camera is a 1D from Canon, the lens is a...
Cephalopods are a very interesting family of mollusks. They can change color and texture in the blink of an eye, spray ink at the face of predators, and eat things three times their size. There are four living cephalopod groups - Nautilus, Squid, Cuttlefish, and Octopus. Of those four, cuttlefish and octopuses are most suited for aquarium life. Cephalopods are naturally short-lived. Their lifespans are governed by the species' maximum size and surrounding water temperature. Aquarium-friendly...
Aquatic Photography How-To
Preface
Over the last year I have become overwhelmed with the amount photographic opportunities that this hobby provides. I have upgraded my hardware 3 times, and spent far too much money than I care to talk about. A lot of this spending was not necessary, and could have been avoided with a little know how, and a bit more experience.
I hope this How-to can help my fellow reefers better understand the ins and outs of photographing their aquariums and its...
