Stability, Friday the 13th & Fish Day 🐟🐟🐟

Fish Day

My numbers are exactly the same as yesterday, so I am going to add some fish today. How many should I add so that I don't shock the system into ammonia overload? I recall the standard being 1" per gallon of water, so:
  • x = # of fish
  • y = length of each
  • g = gallons of water
x = g / y









The Numbers


Date GH KH pH NO2 NO3 NH3/NH4 Temp °C
13-May 180 80 7.5 0.5 40 0.50 23°


Looking back on this graph, I actually could have introduced fish around May 3rd or so; perhaps a little earlier. That is, if I had known about the 0.5 ppm ammonia threshold. Nothing else to report other than the fish are coming. I will probably wind up getting a couple of larger goldfish. At the same time, I am also hesitant to bring goldfish into it this early. From what I've read, they are messy fish and thus, may introduce too much ammonia to the system. I'll try to do my due diligence to figure out the right fish for this system.
