I started adding about 2 gallons of water from the dt and I think the diatom problem was actually Dino’s and the nem will deflate at night when the dinos are in the water column. I changed all the water back to fresh saltwater and will see if it perks back up.
The nem looks good during the day and the mouth is slowly closing more and more every day.
Now trying to rid the dinos in the dt before I move the nem over.
