100W of light over a 25G tank is really overkill. In a tank this small,
you are going to spend your life weeding it out if you are driving it with
that much light. When you add the nutrient levels you'll have with 3 large
fish plus misc. others, you've got a sure recipe for algae. I'd back it
down to a _maximum_ of 3w/g on a tank of this size. I'd also not keep
Discus in a planted tank of less than about 50G in size. They just produce
too much waste with the meaty foods they require.
