How often to feed crocea clam?

Here are a few examples of what the upper margins of the shell should look like. Not the best pics, but hopefully you can see the new growth?

The intensity issue is that I don't want to bleach my other corals. My tank is a 10- gal. Thats nano. The blade coral grow light I have is built for a 40 gallon. 25% on all spectrums is plenty for a 10 gallon, but 100% is overdosing by 4 times. The conflict is that the other corals I have love the 25% but will die/need some time to acclimate in a 100% while clams love very intense light

You can not and should not think of the light in those terms. I am unsure where you got that idea. A 12" blade is not adequate for a 40b tank it is not in any way shape or form enough light. There is no way AI put that on their product. Who put that in your head? A 40b is 36x18x18" a 12" blade is not going to cover that. My return to reefing tank was 32g 20x20x18" I had a 21" blade on it and using a par meter I had to put corals in specific spots to get enough light. In all actuality I should have had 2 21" blades on that tank. So if a 12" blade is good for a 40g how could a 21" be inadequate for a 32g tank? Because it doesnt work the way you are saying and thinking it does. You will kill the clam with that thinking. I am sorry but that is the truth. Take the clam back to where you got it. If they knew your set up they should not have sold it to you in the first place. I know that sounds harsh I am not trying to be mean I just want you to succeed and that clam to thrive.

If you decide to keep it and listen to what multiple people are telling you, you may indeed damage some of the other corals in the tank. Like I said increase intensity over time no more than 5-10% every couple days to allow your corals to acclimate. The most intense light from that blade is 4" to either side of center outside that the par drops off quite rapidly. So if its a standard 10g and you have the light going across the longest portion of the tank then you have some lower light space at the back and on both the right and left sides of the tank. Maybe post a pic of the tank how its set up this may help.

I am not saying you have to go to 100% intensity but you probably should be 75%+ and the clam could take the light from 2 of those blades set at 100% each. And probably should have that kind of lighting for its health.

Cranked up the light like crazy, all the other corals are still happy and healthy. thanks for the info. will soon do 100% intensity

Whoa whoa whoa. I said go easy, slowly, 5-10% every couple days. Not all the way rn! How high did you go?
I mean in all reality it will probably be fine pretty sure the corals you have can handle what the 12" blade can put out but corals dont like drastic changes.

I did 5%, its noticeably brighter and the corals seem happier with that, not noticing any uncomfy corals so far which i assume is a good sign

Yes I am sure it is . I am thinking most of your corals can take that light at 100% but you may need to strategically move some corals to the ends or other places not directly under the light. Clam should be as close a possible to the middle and as high up as possible.

Got any pics?

When i got the clam, I put him on the highest rock and its directly in the middle, so he is getting the highest light possible and will get even more light over the following week or so when 100% is reached
