Try take an upside down photo of your tank sometime. You will be amazed what you can see. Make sure to turn the pumps and powerheads off so you get the most serene surfave for a clean reflection.

Upside down tank shot
Just a little change in perspective can mean a lot! Since gravity isnt as much of an issue when you are underwater, up and down cannot be determined in the conventional way. And with the water's reflective nature, it makes sense to explore and make good use of that!

20141029 Reef Tank Update
Real quick update of my reef tank here. I did some change over the weekend- I decided having 2X 150W LED hanging over the 92G corner is a bit too much for the tank. So I removed one of the two light fixtures. moved one to the center and increased the intensity slightly. So far everyone is happy.

20141014 Roberto's impressive 720 Gallon Reef
In case you haven't seen this thread in Reef central
You definitely want to check out his tank, the planning, the build, and the progress.
It is a stunning tank!

2014-05-02 Discussion: pH Level for Marine Aquarium
You might have heard how important pH level is, but you might not have experienced what it can do to your tank if your pH level is really off target- Well, this winter I've battled the pH war and have a lot to share:
Background
The first mistake- probably a success in many other ways- is that I have my fish tank sitting in my finished basement. The reason for this placement made all the senses when I set it up- basement's air temperature does not fluctuate like that of upper levels, it also has the most solid, salt resistant floor surface- concrete underneath carpet to support the weight of the tank. And an easy access to the nearby utility sink. But I forgot one thing- without any open windows, the oxygen level tends to be lower than any other floor levels.
What does oxygen level has to do with pH? There is actually a very useful article on pH by Randy Holmes here: http://www.reefkeeping.com
In summary, pH is the measurement of hydrogen particles in the water, and the concentration of hydrogen particles relays heavily on the amount of oxygen present in the water.
When pH level is low, the water is acidic, and it will become difficult for your invertebrates including snails, corals, and clams to build skeleton as their bodies must allow the use of calcium carbonate (basic) to help neutralize the pH level within their bodies. (similarly, if a person constantly resides in an oxygen deprives environment, this person's body will be more acidic, and hence be more prone to osteoporosis as the body is unable to retain calcium)
So what happens in my basement over the cold-long winter here in Wisconsin is the low oxygen level due to closed window causes the tanks' pH level to drop below 8.0. This almost entirely stops the growth of all my stony corals and my clams.
To solve this problem, I began employee the help of kalkwasser. Each week I mix 1tsp of kalwasser with RO water per 25 gallon of water volume and pour the solution directly into a high flow area of my tank. This maintained the pH level of my tank between 8.0 to 8.2 through the rest of the winter. With the help of higher pH level, my corals and clams resumed growth and are happier than ever.
With my detailed documented water test results- on a spreadsheet- I discovered the dramatic change of pH level once the snow has melted on the ground and that I was able to open the windows of my house- pH level shut up from 8.0 to 8.3/4 within a week without requiring any further kalkwasser dosing.
So if you have noticed a slow to none growth with your coral or clam despite strong lighting and adequate calcium levels, you might want to give pH adjustment a shot!
