Hi Nano-man,
Nitrates and phosphates are a fact of life in reefs. Phosphates usually come from food and our replacement water. Nitrates are usually byproducts from fish waste and uneatten food.
So...its a given that we have nitrates and phosphates in our tanks. The goal is how do we remove it? Well...algae does a great job, but nobody wants an algae reef tank. That's why we have skimmers, refugiums, activate carbon, DSBs, denitrifiers and water changes. Their purpose is to remove these waste products from our tanks.
Is this for your 8 gallon tank?
