I was curious about how much and how often we all feed our fish. We all want what is best for them, but we also need to keep water parameters in mind when feeding as not to create an unsafe amount of nitrates too quickly resulting in way more water changes than what we may like. I have heard many different ideas on the matter, and I have settled on 2 feedings per day and about as much as they can consume in about 45 seconds or so. I have 12 assorted what I would still consider juveniles, and my feeding regime produces about 2 ppm nitrates per day on average. I can get by with about a 50% water change weekly. I allow my nitrates to reach no more than 40 ppm. At that rate, if I get to 40 and remove about 50% I am removing about 20 ppm with each water change resulting in about 20 ppm remaining. In a week, my 2ppm daily increase will get me back up around 34 - 35 ppm once again requiring another water change. This schedule works for now, but as they all put on more size, or I add more fish, I will either need to increase the amount or frequency of my water changes. I would love to hear what others are doing.
