You are really having fun with these pics, aren't you! It's pretty cool for us to see your tank from the other side of the globe!
Have you tried using fill-flash to enhance the colors in a pic. Sometimes the resulting pic needs to be darkened afterwards on the computer, but it allows a view of the variety of color in the tank, rather than a 50 feet deep blue view.
Thanks for sharing your work.
The sand filter commonly used for pools is a variation on fluidized bed filtration. Fluidized beds are used in aquaria. I think one may be called the Sea Storm, which has tank water pumped up through an inverted cone filled with special silica sand.
Fluidized beds are used extensively in commercial applications for biological breakdown of wastes. The process is also a way to grow bacteria to make products we use in everyday life.
FYI - Citric Acid, an ingredient of many prepared foods, is made by bacteria in huge tanks.
A more unusual product, Xanthan Gum, (the x is pronounced "z" like xenia) comes from bacteria and is a thickener. It gives a little body to juices and sauces.
Sorry if this is boring, but it's my business clients that make these products, including antibiotics to treat infections... bacteria at work again!
Well, time to get to work, finding those people that grow bacteria!
