Wow!  Peter that's a LOT of light!  I've got a 50 gallon with 110w
PowerCompact fluorescents, on for 10 hours per day, and I can grow just
about anything (five different varieties of algae at last count, all doing
marvelously well).  I know Cabomba likes a lot of light but remember that
PowerCompacts emit more lumens per watt than standard than NO fluorescents
(Neil, are you listening?).   With lower light levels you might be able to
ditch the PhosGuard.
