Which of these is killing my freshwater fish: easybalance, stress coat, kent marine pro plant series, aq. salt?

55 gal tank
cool water
lost 3 freshwater clams, a pleco, and a hoplo catfish
also whichever produce it was seems to cause hole in the head
my pH. 6.0 the same as my tap water (well water)
my ammonia is 0

The aquarium salt says that it is for freshwater fish and that it improves gill function and electrolytes.
I have 58 in of fish in my tank

4 female guppies = 3 in
6 zebra danios = 6 in
9 white clouds = 4.5 in
5 serape tetra = 5 in
1 female marble gourami = 2 in
3 freshwater clams = 3 in
3 otto catfish = 4.5 in
1 pleco = 20 in
2 hoplo catfish = 5 in
5 japonicus shrimp = 5 in
total = 58 in

plants

2 tall onions
4 small onions
1 bunch water wisteria
1 bunch hypocorba stricta (spelled wrong)
2 green cabomba
3 anubuis nana
4 java ferns
3 dwarf lillies
1 bunch microswords
1 amazon sword

There are a few possibilities here:

1. The salt was not properly dissolved before it was added to the aquarium. Additionally, as others have mentioned, some of your inhabitants may not handle salt that well.
2. The pH-altering effects from the Easy Balance cause sudden shock in pH and/or hardness. This one seems unlikely though.
3. The clams died because they did not get enough food, and caused a chain reaction. Clams are specialized feeders that often do poorly in aquariums because of the lack of proper water movement and food (microorganisms, plankton, etc), and are notoriously known for causing big ammonia spikes when they die.
