Figuring out what's wrong with your CO2 setup and fixing it is
probably the single biggest thing you can do to get your plants
growing. You may have had a bad reactor or a leaky CO2 system.

What plants did you buy? Hope you got lots of stem plants that grow
fast and suck up nutrients, not a bunch of expensive Crypts, Swords
and Anubias. At least till the plants get established, you are right
about going easy on the nutrients. Even when plants are growing well,
Dupla's recommended doses of fertilizer are too high for many people.

You could also try some inexpensive floating plants like Ceratopteris
(Watersprite) that grow quickly. Some other plants that also grow
fast are Hygro polysperma, Hygro difformis (Water wisteria), Rotala
rotundifolia, Ceratophyllum (Hornwort) and Elodea.

You could get more algae-eating fish, and drop the lighting to 80 W
