I started out using just Excel for my 2.5g nano, then switched to diy co2. I later started dosing Excel again while continuing with the co2, to combat hair algae in my HC.
After I got rid of the algae (which involved daily work with tweezers for awhile, ugh), I kept doing both Excel and co2 together because the growth and health of the plants was simply incredible. The HC and downoi in particular just seemed to go insane. And there have been absolutely no algae problems since.
The tank has 26 watts of PC lighting on for 8 hours daily, and has been set up for about 7 months. In addition to HC and downoi, it has Mayaca fluviatilis, Ludwigia arcuata, Rotala 'colorata', and Anubias nana 'petite'.
