sotomx Posted December 29, 2010 Share Posted December 29, 2010 Enough light, placed at the bottom of my 33 gallon tank illuminated with Leds Par 38 Ecoxotic Link to comment
Squared Posted December 29, 2010 Share Posted December 29, 2010 is this a question? or a statement? Link to comment
paneubert Posted December 29, 2010 Share Posted December 29, 2010 is this a question? or a statement? Looks like a statement. And looks like the clams are happy. I guess it depends on how long they have been there like that. If it has been for a while then I agree with them when they say that it is enough light for those 2 clams. Link to comment
1fishmonger Posted December 29, 2010 Share Posted December 29, 2010 Whether it's a statement or a question - I don't think it's enough light with just par38's...Esp. if they're at the bottom of your tank (didn't see you mention a depth). Hmm... Yeah, I'm sure it's not enough light. Croceas are one of the more demanding species of clam in terms of light intensity needed. They may look ok for now but I can almost guarantee their health will decline over time. Link to comment
sotomx Posted December 29, 2010 Author Share Posted December 29, 2010 Hi all and thanks for your feedback, at the beginning I wrote this as an statement, but now I wonder how long should I wait to see if it´s enough light? They have been there for 45 days and are at distance of 29" from the lamps. Link to comment
Urchinhead Posted December 29, 2010 Share Posted December 29, 2010 They aren't reaching and they are fully open... Looks ok to me... Though Crocea shouldn't be on the sand bed. They need a bit of rock under them because of the size of their gills and the size of your sand... Plus they will attach to the bottom of your tank with their foot making it impossible to move them. If they have already attached then you can slide a flat rock under them a bit so that they gradually move up onto it. Link to comment
RayWhisperer Posted December 29, 2010 Share Posted December 29, 2010 No expert on the subject. However, I'm guessing it would not only depend on depth of tank, but also how high above the light is, as well as optics. Link to comment

sae647 Posted December 30, 2010 Share Posted December 30, 2010 optics ????? this makes a huge difference. Link to comment
sotomx Posted December 30, 2010 Author Share Posted December 30, 2010 ????? this makes a huge difference. 40° 3 whites 2 blues each. Link to comment
anizato Posted April 23, 2014 Share Posted April 23, 2014 would a clam do well directly under a par38 in a regular 10gallon tank on the sand? Ecoxotic PAR38 4" above water. Link to comment
doppelganger Posted April 23, 2014 Share Posted April 23, 2014 This thread is old... but yes a par38 would be fine assuming you know all the other aspects of keeping a clam like type, calcium demands etc. Link to comment
anizato Posted April 24, 2014 Share Posted April 24, 2014 I have a 10gallon NANO reef. I have read and been told on several accounts, that dosing on such a small tank would not be ideal. Instead 25% weekly WC would do the trick. Is this so? What is the truth behind this? Any ideas? Link to comment

Instead 25% weekly WC would do the trick. Is this so? What is the truth behind this? Any ideas? yes this is true. In a 10 gallon, water parameters can change more quickly because there is less water. Clams can majorly suck up calcium so you'll have to supplement that with either water changes or dosing. It really depends on how much calc, alk drop. The safer option is water changes as dosing can usually can be more a headache (if it's not automated) and have a larger chance of things going wrong if not done properly. I'm hardly a clam expert tho. There are many ppl on this site who are so I think you'd be better off starting a separate thread of your own asking for advice on the topic. Include some basic info on the setup you want to run and your experience. If you do enough research, I'm sure you'll be fine. Best of luck! Link to comment
