3 tablespoons, added 1/2 Tbsp per day.  

Mollies and cories are not the best companions.  Mollies like their water
hard, alkaline and saline.  Cories like their water neutral to acid, soft
and relatively salt-free.

What is your tank temp? If it is below 80 F that could be your problem.
Also, do you feed live brine? If not you should. The lack of live brine
can also be a problem.  Also, Do you feed them PLENTY of veggies
(esspecially spinach?) If not then that IS why they are dying.

Formula for successful mollies:

80 F + 1 tspn NaCl/gall H20 + spinach|zuchini rind
    + live brine = HAPPY MOLLIES THAT LIVE LONG AND MULTIPLY (like crazy)

Mollies like it warm (78-80), and salty. I used marine salt, 1 tsp/gallon,
for my mollie/cichlid tanks, that's not all that salty but it seems
to keep them happy (they spawn, an occasional fry makes it to adulthood, they're
never ill,...) A 2.5 gallon hex is a lousy tank - it has the surface area
of a teacup. Get them a bigger tank, like a 5, normal dimensions. You can
put a small submersible heater (I like Ebo-Jagers) in it, along with a home-made
breeding grate. To make the grate,
use aquarium-safe silicone sealant and glue two strips of
clear plastic corner molding to each long side, about 1/2 way up.
After two days, you can rest a piece of fluorescent egg-crate grating on it.
Put in a sponge filter that's been aged in an existing tank. Put in a bunch
of scrufty java moss below the egg crate. Insert mollie pair. Stand back.
The egg crate prevents the parents from getting the babies. Wait till they've
spawned, and you can remove the parents and grate and have a good rearing
tank. Don't forget the salt!

If you keep the temp steady and keep salt in the water you should not
get fungus outbreaks, and your mollie should be a good size.

A few weeks.

Live food - they *love* newly hatched brine shrimp, adult brine shrimp.
Some folks feed 'em sewer worms like blackworms and tubifex, but parasites
are always a threat with those foods.

Makes sense, but a 2.5 hex is a lousy rearing tank.

I'd cut a hole in your hood if I were you.

All the mollies I've owned had serious problems with fungus all
their lives.  It comes on and off, but with mollies (esp. black mollies)
it's more on than off.  Raise the temp to at least a constant 80 deg.
I've found that if you raise the temp to the 85 deg range, mollies
tend to not have problems as much, but other fish might not like that
temp.

If she is well, she should be able to have batched of fry about every
1.5-2 months.  She may be getting old--I had one that stopped baby
making after about 1.5 years.

The little ones love big tanks all to themselves.
