I have a 3-gallon tank with 26-watts of CF light, an Aqua Clear HOB (rated at 100gph) and Eco-Complete substrate... I dosing Excel for CO2, but am wondering if EI works at this scale? Should I just divide EI down to the tank size and dose like normal? If so I will have to make some dilutions, as dry dosing at this scale would be very hard...

I do EI dosing in a 2 1/2 gal tank. I mix about 10 doses worth of each fert in a little bottle, with 10 capfuls of water in it, then dose a capful at a time. Seems to work fine.

ok, i think i will do the same then... Thanks
