is it even worth my time to set up a diy, or should i just go straight excel. will eventually get a different light fixture, but trying to get the science down on the 30g 3.2 wpg before i jump into another.

thanks for all your help!

flourish works well on anything below 2 wpg, I would just use that for now until you upgrade your lights.

If you feel like bothering with it, then I think it's worth it. On my old 6g with 8w, you could easily see improvement with CO2 vs Excel.

A DIY setup is pretty simple and cheap to make. For the price of a 500ml bottle of Excel at Big Al's you can buy enough yeast and sugar to last you six months (longer if you shop at Costco ).
