Kelly - I did not ever claim that this is gospel!! NOTHING in this hooby is. That includes your own statements. The claim that my statements are wrong are no more factual than my own. All statements made in this BB should be taken with a grain of salt. Obviously because I hold the minority opinion on this subject most will ignore my rants about how corals need light. But when people start to really look at the biology of these creatures and realize that they can adapt to, but are not doing optimally in, 32watts of light, people will start to come around.
If you read my posts you would see that I never said that one cannot keep a tank on low light, just that it will not be as healthy, as an equally maintained tank with more light (assuming the corals kept are photosynthetic).
I also stated that one could do a deep water tank, but as I said it would be very difficult to do (especailly in a nano envirnment). This would be an exceptionally BAD idea. The amount of feedings required to maintain corals like Tubastrea, Non Photosynthetic Gorgonians and Sponges will quickly ruin the water in such a small tank.
My real point, that I have been trying to make since my first post in this topic, has been that Nanos are not a way to save money by getting $50 worth of light. Mushrooms and polyps can be kept in low light. So can anything else, but it does not mean they will be healthy or happy.
Frankly my problem is not with trying to maintain a tank on low light... it is with ising out dated rules like WPG to justify it as a high light envirnment. People putting SPS, clams, and anemones in tanks with 32watts of light, because they read here or elsewhere that these animals need 5-7 WPG (or whatever), is really sad. Most will be put in and slowly die. The animal may even grow while it is dieing. Growth does not ALWAYS imply health. People post questions all the time about their anemone, in a nano, walking all over the place and not being happy, then dieing.
This hobby, for me at least, is about the understanding and preservation of these creatures, I think people will have more sucess with higher light than low light.
