Is this PMD ?

[AdamKo]

Hi guys.
Need advice for PMD.
Is this it ?
My clam is around 3". I got it for a two,months or so. Params are pretty stable. Nutrients practically 0.
Luckily I made icp week ago.
Acroporas and other corals are fine.

I would like to perform 30 min FWD, and scrubb off this algae on the shell.

 

[OrionN]

I think it is injury related, not PMD.
PMD only transmit from clams that is infected to another one. It does not start in healthy tank.
There are many other cause of mantle irritation which result in transient retraction of mantle is specific area.
There seem to be something in your tank taken chunks of the clam mantle

 

[AdamKo]

I will be watching to see who is responsible for this. I will still wait with the dip.

 

[AdamKo]

Could be low kH an issue ? I got the feeling, something is "clicked" and dKh dropped down to 6.5... it was not a swing, rather slow drop. I'm increasing kH slowly by increasing balling dosage

Is the clam growing?

It is impossible to tell from this picture.

 

[Tahoe61]

I would move it away from that large lps. The LPS has the potential to put out long mesenterial filaments that can sting near by inverts.

 

[AdamKo]

I will try make better photo tommorow.

I will. Thx. Despite the flow goes other way.

I would. Having had LPS destroy other corals I take no chances. The may make it look like the LPS is closer to the clam though.

 

[AdamKo]

Clam has been moved. Other photos, also scrubbed some algae. When I will be sure the clam is ok and algae free I will glue it to rockwork

 

[OrionN]

That clam is not growing.
I would advise against glueing it to rock.

A clam is a living animal that can and will move on its own, you can't glue it to a rock.

I mean glueing the rock basis, no clam itself.

How can you tell the clam is growing or not ?

 

[Tahoe61]

The upper margins of the shell would show new white shell growth.
Personally I would advise against removing the normal film algaes and corailline algae that grow on the shell.

 

[AdamKo]

Thx for reply. I am removing GHA. The little amount is attached to the shell, and grows,bothering mantle I think. When the coralline algae will grow on the shell I will be fine with this.

I think it’s in too low of lighting and it needs some nutrition. How often are you feeding your fish? The clam doesn’t need to “eat” but it does need nitrogen and the lack of nutrients tells me you can probably feed your fish more, increase the lighting (to the clam) and hopefully it will start growing again. People often get maxima and place them in the sand thinking they need to be acclimated to your tank’s lighting, when in fact, the clam has probably been starving for light (at vendors or wholesale) for too long, only to receive the same or less lighting in your tank. If there isn’t new shell growth when you purchase the clam, then it’s been starving for a while. Either avoid buying that particular clam or have the conditions the clam needs asap. They need lots of quality light.

Thx, I have moved it higher and feel it's better now, wider opened.
I got 2x xr15, 100% power, and 4xt5 bulbs. Fishes eat 2, 3 times a day, However my nutrients are very low, almost undetectable (NO3 0.1 and PO4,0.06 due to last ICP), I have to dosing ammonia to rise nitrates. Every evening I pour coral dry food, phyto mix, and TM phosfeed. Maybe should I dose some low grade coral/clam food during a day when the clam is opened more ?

No need to feed the clam itself, just the fish and the system as a whole. Light is the number one priority and what you’re adding is more than enough nitrogen for the clam. Look at your corals, they’ll tell you if they are healthy or not, the numbers (nutrients, etc) are just a snapshot of the current state of the tank. I don’t reef by numbers, but animal health. The numbers will depend on the individual tank and its inhabitants and they will be different for each tank.

Appreciate your reply. Agree the tests are snapshot of tank at certain moment. I am in the process of adjusting the balling dosage for system consumption. Recently I have increased the dosage more than twice already, and still the dkH is below 7. I measure the alkalinity daily. I also avoid rapid changes. Corals look healthy, polyp extension is good , noticeable growth of acropora, although they are still only grafts.
I have already removed practically all filter media from the sump due to low nutrients. All that's left is activated carbon, which I replace every month, and some live rock, which is already years old, overgrown with dense sponges, so I want to leave it. Ammonia doses because without it po4 builds up.

I think it’s doing better now thx guys for help
