LR Crumbling

[sw65galma]

I have a piece of LR that has an archway...But everyday i keep seeing more and more pieces breaking off.
Would low calcium cause this?
I don't have much in the tank but damsels, my red general star which always stays on the glass and my brittles.
That's it.
thanks

My first question would be ...what is your calcium level....you gotta give us more specs.....
My second question...why do you have Damsels,...are you still cycling?
And third...?? One piece of live rock?.......

PH:8.2
Nitrite:0
Trate:80 (still working on this grrr)
Ca:180
Alk:200
Salinity:1.021 (trying to get it higher slowly)
This is a FOWLR.
The reason I still have the Damsels is that I really like them
They were my first SW fish and *knock on wood* i haven't lost a single fish yet..And I don't have the heart to get rid of them, I got 10 of them! and they are all good friends which is rare for Damsels. Although they have a 65gal all to themselves.
I have a yellow Tang and Orange Striped Angel in my 46 and 2 clowns that can go in the 300gal when it's done..hopefully soon.
