60 watts is low for that depth of tank, but it'll grow a descent set of 
low-light plants. The swords love lots of light. AH supply sells CF at 
good prices, if you so desire.

Depends. I keep mine at 3.5-4.5dK. pH values never drops below 
6.6 or 6.7.

Need more, 5-10ppm. Plus the K is an added bonus.

Good. Sounds rich. Spike the heavy root feeders. The rest get 
along fine.

Swords and crypts may need the Jobe's, but the others will do fine 
w/o them. Small pieces of Jobe's plus a good level of NO3 in the 
water should bring everything to green. Small amounts of ferrous 
iron are needed, too, but it's probably in the Dupla24 mix. Check 
your K and Mg (if you can). If not, add a little K2SO4 and Epsom 
salt to the tank. Little additions over time, not a big change. You 
should notice a difference in a week or two.

Good. Try to score some Otos and SAEs, maybe some type of 
shrimp. Heck, everybody else is doing it! ;-)

Good luck, Craig. If all else fails, we can go to Mitch's house and 
swim in his tank!!
