Sanjay, I apologize because I know this has been asked before, but for the life of me I couldn't find your response.
What ballasts are you running your Giesemann SE lamps on? I seem to remember you might be using IceCap electronic ballasts for these lamps, is that correct?
Thanks.

hi sanjay - just to expand on the lighting question above... you are *not* running actinic supplementation, correct? and which giesmann bulbs? (i see 13K and 22K bulbs listed at Marine Depot.)
also - this may be a dumb question - but why run both forms of media (both schuran type and ARM) in your Ca reactors?
how often do you monitor your ALK and Ca? how often do you have to change media or unclog your reactors?
thanks for any help!

The bulbs are sold as Giesmann Coral. The K rating is no where on the box. They do test out close to 14K, and hance are a crisp whitish blue looking unlike the so called 14Ks that have a predominent blue color.
Yes, I am running them with Icecap Electronic ballasts.
The bulbs are now about 17 months old and due for a change.

Sanjay, amazing photos as usual. i have just finished reading your photo taking article http://www.advancedaquarist.com/2008/5/aafeature2 but you didn't let us in the secret of how you got most of these photos. they do not appear to be top down, and how do you get the fish to hold still in what is a very shallow depth of field?
do you use a flash that is not mounted on the camera?

Here is a link to a description of the bulbs and k ratings. But in the sale part it says nothing about k rating. Instead it gives a m number. Maybe you can figure out what ones you have from it.

I was going to order the 13k Giesmann bulbs but now am undecided.

To get the fish to hold still in the picture, the key is to use a fast shutter speed. I usually use 1/200sec. What this means is that to get more light, the aperature will have to be bigger (smaller f stop) and thus decreases the depth of field. Often there may not be enough light due to the aperture setting required for proper exposure of aperatre setting required for the depth of field. In these cases, I use a flash that may or may not be mounted on the camera. With my Nikon D70 and Sb800 flash I can use the flash off camera as it can be triggered wirelessly.
The other keys to good photos of fish is to make sure you camera is parallel to the glass plane, and that you have a good sense of the fish movements and how its going to behave and where it tends to move in the tank. This allows you to anticipate when to trigger the camera.
