I recently dosed my 3 foot tank with No Planaria in my 120L/3ft taitibee tank. I dosed under the recommended dosage but after the 3rd day started seeing dead shrimp. It was only 1-2 on day one so I did a 40% water change and added an internal filter with carbon to try and get the rest of the no planaria out of the tank. It's day 5 now and I'm still seeing shrimp deaths. Yesterday was the worst with about 10 and this morning was 5 found dead. I always seem to find them in the morning and none seem to die during the day.
Tank has 2 large sponge filters and a internal power head filter(normally don't use this one but needed for the carbon). I have added an airstone today in case it is lack of oxygen. Tank is planted but not heavily. Mostly java ferns, anubias and subwassertang with a few floating watersprite. Ammonia 0, Nitrite 0, Nitrate 20, KH 0-1, Gh - 4, TDS 120.
How long would it take to get the No Planaria out of the tank and are these deaths possibly just residual from the initial dosings? I'm doing another 20% water change today and hopefully the deaths will stop soon or is it possible my whole colony is doomed already? Remaining shrimp seem to be acting fine and haven't seen any odd behaviour in them at all.
Any advice is greatly appreciated and thanks in advance.
I need an explanation to what has happened to me ... today, some beautiful Black Panda came home, they were all alive and very active, the water temperature inside the bag was 19.8 degrees Celsius so I started the acclimation with the temperature leaving the bag floating in my tank but open for oxygen exchange (the bag was a breathing bag, is this an issue? It was open…).
In just 30 minutes the water reached 23.5 degrees (could be this an issue?) so I started with the drip to match the parameters of the water and only half an hour later there was a dead shrimp, after this death all start to die in a period of 2 hours.
The substrate is Glas Garten (PH 5.8 max), I use Bee Shrimp GH+ (TDS 130 - GH 6), I checked before Ammonia, NH2 and NH3 and all were in zero. The shrimps came with a PH 6.8, GH 6, TDS 155.
Two weeks ago, I was doing some maintenance in the tank and I broke one small hydrogen thermometer dropping all the small metal balls in the water, so immediately I sucked all the balls with a pipe removing also a big amount of soil. Could this thermometer poison my water? I took some of my Neocaridina shrimps in a bag and I added this water and they look fine, why the pandas died?
Should I set up the tank again from zero?
