I'm kinda confused or it might be that my answer was confusing.So would it be safe for me? I see that ur using atleast one fert :S.
CO2 is a kind of nutrient. By injecting CO2 without a corresponding increase of other nutrients, those other nutrients will be depleted down the road - creating an imbalance of nutrients. With such imbalance, many plants may not be able to grow, but algae can. Thus, algae may become an issue.Can I add DIY C02 without adding ferts to the tank?
Alright, I see what you're getting at, but can't I just give them none of both and they'll still do good? Because I have an ultra low light tank.think of it this way...
co2 is like water to us and ferts are like breakfast, lunch and dinner to us.
you can live on just water for a short while, but you'll still be starving for nourishment. and will eventually perish.
plants are living entities and they need nourishment to survive. so do them a favour, provide the nourishment.
