light requirements tridacnid clams, isnt about time we put some science in the mix???

light temperature, tank depth, water quality, hieght of lamp above the water, disolved organics, surface aggitation, etc, etc.... all change the light intensity delivered at a specific depth and location under various lights(color) It would be most helpful if we ,the aquariast and the "experts", would measure and report in Lux and light temperature. Lux meters are inexpensive and easily shared ie bought by local retailer and loaned to patrons. If anyone can provide their lux measurments at this time I would like some feedback. Thank You. My first contribution to Reef Central :)
 
WELCOME to the forums richard!!!!

it is alitle annoying to return to ones thread just to see someone has said "do a search or else!!!" lol.....lol

oh and lewboski I don't think the thread you linked to really ansewed or even addressed the issues Thr thread starter was asking about....
 
Ahhh.....this must be the infamous Dr. D that all the best corals at my favorite LFS are marked sold for. Heard a lot about your tank, glad you have joined RC and can't wait to see the pictures of your tank.

Sorry for the off-topic post, but I would like to know this info as well, would like to get a clam someday, but only after I have learned a lot more about them.

Answered some of them.:)

RonN I was giving him advice for the future.;)
 
Poor LFS

Poor LFS

I have a feeling that the LFS just lost a lot of money! Doc, check out the sponsers of this site! I have been buying a ton of stuff from www.ReeferMadness.us. Check them and others out. It seems weird to get livestock overnight but it is no different than how your LFS gets them. As for clams I would get HUGE Derasa if I had that large of a tank. I have a 12' inch one and made it the focal point of my tank.


Good Luck
 
First of all I thank everyone for their replies. Second, lebowski, I did not mean to imply that Lux and its use is new science only that reporting it as scientific data would be very useful. I have seen many threads discussing Clam placement, lights etc. For example " I have a new maxima and have placed it 16" deep under my new 175 watt XM lamp. Is this appropriate lighting?" (Hypothetical Thread) Using more emperic data we could better assess the thread..... "I have a new maxima and have placed it in a location 16" deep where it recieves 8500 Lux from my new 175 Watt 20K XM bulb. Is this appropriate lighting?"
 
oceanarus it is I the infamous Dr D. Are you breeding the friedmanies?

Lazy reefer, I currently have many clams(ten last count) I like to keep an eye out for special clams and corals if find one I like I will give an older one or one that has out grown its usefulness to other reefers or the public aquariums near by. The problem is I have very seldom seen a clam I didnt like.

Got a pair from Tideline a little while ago, they are doing well, but I'm sure it will be some time yet before they start spawning. My wife and I do raise all the small ocellaris you see at Tideline (as well as most of the other stores throughout the state). We also have a number of other pairs of clowns, so we'll be selling tomatoes, cinnamons and GSMs soon.

Still can't wait to see the pictures of your tank!
 
Wow, you will fit in great here. Sad part is... you may not be the most educated person you talk to. I am truly amazed by the CPA's, MD's and other PHD's that visits the Reef Central boards.
Kinda makes me wish a took a tech. writing class.
You getting this Leboski??
 
Richard,
I completely agree with your sentiments but unfortunately very few reefs own or even have access to a lux meter. When asking a question such as the hypothetic example you used, people are asking for a general response, sure they may have high DOM, surface agitation etc. but an assumption can be made using the average conditions in a tank that is suitable for clams. This assumption would be a long the lines of clean water, slight to moderate surface agitation, bulb approx 10" above the water (therefore clam is 6" below the surface).
Statements about the animals we keep are often very broad e.g. the general statement that "SPS" require high lighting despite the fact that "SPS" covers several families of corals with very different requirements and different natural habitats. This is also true for statements about clams in particular the general rule that clams must be 3" before they are able to obtain most of their nutrients from light. This ignores the fact that different species grow at very different rates but probably aquire zooxanthellae at a similar rate.
 
firechild I agree ,if a lux meter is not available, a more detailed description of tank perameters will help considerably. However, I still believe and encourage Knopp, Sprung, Nilsen and those of us who do have one should report this value and therefore begin to narrow the general, and establish the extremes of suitable lighting. I believe I've beat this horse enough thank you all for indulging me. Dr D
