Derasa clam with Kessil A160?

[roblox84]

Can I keep a Derasa clam using a Kessil A160? If so, would the light have to be turned up all the way and the clam at the very top or would it be able to be kept at the middle or bottom of tank? Thanks.

Looks like it could work. No one seems to have a par meter but I did find a lot of folks who have used them..

The 160 is pretty weak. How deep or what size tank, etc?

You can keep it on the bottom of the tank with the UV at least 60%

20 gallon tank, 18" deep.

Derasa get pretty big and fast, so I hope you're planning on a bigger tank at some point? Also, derasa will have a weak attachment, so it should be placed on a flat, solid surface or on the sand. Ideally, it should receive at least 200+ micro moles or more for at least 8hrs a day to be happy. But you may get away with a little less? Make sure you see new shell growth constantly, as these clams never stop growing and their growth rim on the upper margins should always be stark white. You may be able to place the clam close to the front glass to get a little extra bounce from the glass, which will increase the intensity a little more, but I'm not sure it will enough in that deep of a tank. They're pretty adaptive, so you may get lucky? If you don't see new shell growth within days, then you know that you're not providing the clam with enough light.
If you haven't done so already, I would buy James Fatherree's new book on clams from Amazon. It's usually around $36 and worth every penny (and more).

You’re fine bro

As long as it's not mounted very high, you should be ok, but it wouldn't be my first choice. The mantle should be outstretched and the clam opened wide.

Derasa love light and you really can't give them too much par. The lowest lighting I've ever kept a Derasa in would be a Kessil 360WE (older version of the X).

Just keep an eye on it for a bit. Would love to see some pics sometime. I like the smaller tanks as they're like a piece of table art.

I'll just say I was never able to keep a clam alive more than a few months. Now that I have a par meter I know why. It's the best investment I've made in the hobby. I currently have a Derasa on the sand under 300 par and a maxima a few inches up on the rocks under 350 par. Both are thriving. I don't know if the kessil would put out the par needed?
Maybe a rock dwelling clam higher up

Just keep an eye on that clam shell, you should always see that nice white layer of new shell at the top. Always. If you don't see shiny white, then its a problem.

I have AI primes I can swap the Kessil with to get more par if needed. But the thing I was worried about with cranking the lighting up are the LPS, Cyphastrea, and a couple other lower light coals I have that I'm not sure how they would react under more intense lightning.

If you want to keep a clam, priority number one is light. If you’re concerned about other corals getting too much light, then maybe reconsider keeping a clam with lower light animals. Sorry to be blunt, but this is the reality with keeping clams. Simply put, clams need a lot of quality light, that amount will be determined by the individual clam. Not providing the clam with enough light will result in the clam perishing. There’s no way around this unfortunately. You could slowly increase your lighting intensity, allowing the other corals time to adjust, but this will only work if the clam is actively growing.
