Thanks reefnut, promise, and murph. I am running carbon and going to do a 30g water change again tomorrow. Inretrospect I think the lighting switch was too much for them in combination with the trites and trates going up as well as the low pH. I am trying hard to correct everything and get it back to as stable as it was.
Today it looks as if my A. convexa and my A. samoensis may have some STN, along with one of my monti caps. Gonna keep a close eye on em do the water change. Post an update tomorrow.
Thanks again for your help everyone.
