First, Carnage
On Friday morning I was counting for my 7 rummy-nose tetras and could only find 6. I counted over and over and looked around the tank and could only find 6. I assumed one got sick, slow, or dead, and my cleaning crew got rid of him. I thought that until I was cleaning water from the floor after today's water change when on one of my drying swipes with a paper towel, I brought a dried-up carcass of a rummy-nose into view. Death comes often in the fish world, I'm not emotionally attached to the fish, but it still shocks me to see one dead. On the bright side, this fish's last act was quite spectacular because for it to jump out of the tank during my Thursday night cleaning it would have had to jump at least 3 inches out of the water to clear the lip of the Eclipse 3 hood. It probably jumped much higher if it didn't have the perfect angle and if the water level was down at all from the water change.
Food
I went to the LFS today to buy food and garlic. Thanks for the recommend Chevelle 67, my LFS had that exact product you recommeded and I bought it. I also picked up live black worms, and a cone feeder. You will see in the pics, they really liked the worms. I also did a mid day feeding with the garlic right on a cube of Mysis Shrimp. They typically like the mysis anyway so I didn't observe a noticeable interest in the garlic-dosed food, but I will keep using it religiously just in case and also to get it used up and out of my house; it stinks through the glass bottle!
Environment
You can see from the pics, the gravel has been eliminated. I also picked up FW aquarium salt while at the store and added the recommended amount. The only water parameter change since the Thurs water change was a slight uptick in the pH from 6.2 to 6.4 as a result of not adding the discus buffer. Also, I did a 50% water change today using tank temp water through python hose and dosing for entire tank volume with Prime. From now on, this is how I will do my water changes until I indicate otherwise. I hope to get 2 50% water changes in per week.
Discus Health
You can be the judge in comparing the pics, but I believe the discus are getting healthier. Their colors are a little better and they are thickening up (the blue diamond more than the turquoise). I expect this to be a long process to get them to a state where they are the stunning discus they can be, but I can stick with it as long as I see positive change. I've made so many changes in the last week that if they do start to turn around I won't know exactly what helped; very unscientific

Photography
I don't think the pictures are very good which may be largely user error; suggestions there are welcomed; I'm using a Canon Power Shot A590 on Auto mode with flash off.
