I'm having a massive Red Cherry Shrimp "knock out" right now and I need some help on nailing down the cause. I say "knock out" because they don't appear to be dying just yet...
Tank Info: 30 gallons, I just topped it off with 6 3/4 quarts of room temp RO.
Water readings after top off: CO2 reading is sitting at very light green almost yellow, Ammonia 0, Nitrite 0, Nitrate between 15-20ppm, KH 12 degrees. This is the standard that the tank has been maintained at for more than a year and longer than the shrimp have been around.
Dosed my normal dosing for today, from the Seachem chart: 2.3ml Flourish, 4.7ml Potassium and 2.8ml Iron. I realize now that I should have dosed Phosphorus today, but I oopsed and did Potassium, I am certain that I dosed the correct amount though. As far as I'm concerned, there should be no issue there... I've been lazy before and just dosed all my macros and micros in one day with no issues.
The only thing that was completely different today is that I tossed out my old bottle of Seachem Iron because it had what looked like slime floating in it. I pulled out a new bottle and dosed from that--I also noticed that my old bottle had become MUCH darker in shade than what was in the new bottle.
Within 10 minutes, as I was removing the annoying duckweed, I started to see the RCS falling from the plants to the floor. They were jerking around much like mosquito larvae as they fell. Most came to rest upside-down and lay there stirring just a little here and there. My Amano shrimp started to do the same.
40 minutes I ago changed out 30% of the water with my tap water and did a free-iron test which came out as 0. The chelated iron test is at 0.1 mg/L. I just now, after typing the above, checked on the tank and it appears that most of the shrimp have righted themselves and are just clinging to whatever they're on. Still not sure they're going to make it, those that try to swim are still jerking like mosquito larvae.
