I present to you a mystery who done it.
My green rasbora's have been in quarantine and fattening up nicely since just before Christmas and I want to shut that tank down, so I did the same as I do when I add shrimps to the tanks.
I did a 50% water change before co2 comes on in the morning to reset any build ups, add ferts and 2ml of glut and then did another 50% water change at co2 off to take of as much co2 as possible, add ferts (2ml tropica green) and 2ml of glut.
I then catch the shrimps/fish I want to transfer and drip acclimate them, 2l of current tank water to 8l of new tank water over around 2 hours, I leave them for an hour and then net in the fish/shrimp and top up with the mixed water. I watched for around half an hour and they settled fine, no red gills, coloured up well, started to test the tank.
The tank when I first added shrimps at around 3 weeks old I suspected was still going through an ammonia spike that I didn't pick up on the test strips, so when I first added shrimp as they were all at the surface every morning, I'd do a 50% water change after about a week of finding them like this every morning things settled and they'd be doing their normal shrimp thing every morning, Hurray.
So today I get up, do my thing, peer at the tank and find ALL the still living shrimp at the surface, half a dozen dead shrimps stuck to the filter guard and ALL the fish going in circles gasping at the surface and a couple of crispy jumpers. 50% panic water change. Everything back to normal, you'd think nothing happened.
First thing after the water change, is check the co2 timer, wouldn't be the first time I've knocked it or one has failed on, Drop checker is lime/yellow, everything a-okay on the timer. Add a second drop checker and make sure it's definitely not co2, still blue after 2 hours, original drop checker still yellow.
Grab the test strips for a quick and dirty, nitrite, nitrate, ammonia, ph, nothing unusual, all undetectable on the kit. Ph 6.5.
So what have I done in the tank that might cause a spike in something, well, nothing that I can think of. I did a BIG trim last Sunday and of course, the big water changes to reset the tank. The shrimp were happy prior to today which is why I was confident to add the fish.
Other notables - the tank is a mix of aquasoil Amazonnia and Tropica.
Tank has some start up algae, namely a reallll mean case of staghorn.
Co2 is via a jbl inline and it's kinda "squirty", not really a proper mist.
Filter is an experience 150. Was seeded with a mix of mature filtermedia and a good squeeze of mulm.
I dose 2ml every day of tropica green and water change every 4th day.
What are the obvious things I'm missing?
It's gotta be co2, right, but how? It should have been reset by the water change.
And what to do now to fix this mess?
