Excel will provide a source of organic carbon for the plants. But it doesn't have the effect of lowering pH. Also I'm not convinced it works that well in high light tanks.

It is a good alternative for a smaller medium-light tank, but becomes uneconomical on anything over 20-30 gallons. I also feel that it is not a great idea for a high-light tank.

I agree, and also want to mention that you do NOT want to overdose Excel. It's a sugar alcohol based carbon, and OD'ing can and will kill fish.

I was using Excel on my 90g for a while. It cost about 20 can a month. I got good growth, but there was nothing that was really hard to grow. When I switched to pressurized CO2, I noticed pearling and increase in coloration and growth rate almost immediately.

I would recommend Excel for smaller tanks with around 2WPG.

Excel works great on lower light tanks as stated.
You Can have adequate growth in high light as well. not near as good as real co2 but it does work. As stated do not overdose or you will kill lots of things! My dad killed 90% of his fish and plants one time by pouring 10 the rec dossage

Dosing instructions as per your request! Copied from Seachem:

DIRECTIONS: On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 gallons*). Thereafter use 1 capful for every 200 L (50 gallons*) daily or every other day. Dosing may be slowly increased in high-growth aquariums. For smaller dosing please note that each cap thread is approximately 1 mL.
