I had the pleasure of meeting with some guys this weekend and the conversation came up about my new pond build. We were talking about the amount of K1 that was needed for bio filtration. I mentioned that I was going to have a 275 gallon tote with about 24 cubic feet of k1 in it. Pond will hopefully be between 8 and 10 thousand gallons. One guy mentioned about the nexus filters,,,he said in the directions it said to let the media mature,,, if it was really dark brown,,,to add more k1 but if it was really light,,,take some media out. Most of them thought that it would hurt to have the 275 gallon tote full of aerated k1 because it would not all mature and grow bacteria. What do you guys think about this? Is there such a thing as overkill for K1?
