Thanks for asking, after I dosed the hydrogen peroxide I lost one and two shrimp a day a week later until I lost around 50 cherries and the 4 CRS I just bought. I am thinking that the hydrogen peroxide made the tank recycle. I did the hydrogen thing again this week and got the same results; the Ammonia has skyrocketed. I lost more shrimp. A buddy thinks it is because I just added Amazonian 2 and he thinks it is from it and to check my levels again in a couple days and not to dose or W/C until then. I did a 20 % W/C with water from my 72 gallon to try and take some ease on the shrimp.
