My tank is really looking great. My light to nutrients to co2 must be in good balance. Almost no algae growth. Great plant growth happy fish. Heres the rub. I want my glosso to spread out. I am adding another t5ho light. I know to keep the balance i may need to increase my nutrients and co2 production. Right now i use 4 - 1liter bottles, i change each of them monthly. I want to increase production without increasing depletion rate. I think i should swap one or two of the four with 1.5 to 2 liter bottles. I would increase the sugar and yeast in proportion to the water in the bottle. Would this increase co2 production? Or would it be better to add more 1liter bottles?
