So these may be some pretty newbie questions but i would feel more newbie by being prideful and not asking. 1. If i am overfeeding, would i see a rise in nitrate and phosphates or possibly ammonia and nitrite? 2. Does it do me any good to test my water right after a WC or am i wasting test solution? 3. How often should i do a WC if i am seeing 0 phosphates and 0 nitrates? 4. Could I be seeing 0 phosphates and 0 nitrates due to the diatom, hair algae, and cyano, or would the small amount of macro in my fuge be making them 0? It doesn't seem like there would be enough macro to keep those levels at 0 especially with all the crap algae growing in my DT, and I would think if my levels had been too high the nuisance algae would not bring them to 0. Anyone who can clarify this for me would be greatly appreciated.
