Aluminum

[CNDReef]

I read that aluminum will make leathers close up. Is that correct?
Also have a gorg that is closed up as well.
The toadstool and gorg keep shedding all the time, could that be from aluminum?
If so what can I do to remove it besides 20 water changes

Leathers close for many reasons.

Do you know that aluminum is elevated?

I show the effects of dosed aluminum here:

Figure 4. The leather coral in the test aquarium after addition of aluminum. After the addition, it cycled between the look in this photograph, and that shown in Figure 3.

I haven’t tested for it yet.
I know something is up since they won’t open up for more then a couple days a month and shed a lot. I also lost a monti digi colony but everything else seams fine.
