My devil's hand isn't doing well. It hasn't expanded in about 2 months, right after I changed my T5 bulbs. I have had a problem with cyanobacteria and having been battling it with water changes and vacuuming the sand, scrubbing the rock. The devil's hand has some red spots on it, looks like it could be the cyanobacteria. I will post pictures later when I get home from work. Can I use a soft toothbrush to help or what about a freshwater dip?

I have 3 koralia's in the 75 gal tank. 2-#3s and a 1400.

parameters:

pH-8.4
ammonia-0
Nitrite-0
Nitrate-0
Phosphate-0
Ca-400
KH-12
Salinity-1.025

It could be the cyano, or it could be shedding. Most (maybe all) leather corals shed and when they do it's a brownish color.
