Yesterday we purchased 110 L aquarium to put half the fish from my old community tank into. These are the fish that are not going into my new planted set up.
We removed all the decoration from the old system, some of this was put in a bleach water solution with a 1 to 10 ratio, soaked for 10 minutes and then scrubbed rinsed and soaked in freshwater.
Meanwhile the fish were bagged up and floated in a barrel which had new water, heater and the external filter circulating.
I then drained all the water out of the old tank and collected all the substrate in a bucket, I washed the substrate for over 20 minutes until every bit of dirt had gone and it was completely clean and the water was running clear.
We then put the gravel, ornaments, heater , external filter and filled the tank with the pre-chlorinated heated water.
I then covered the surface of the water with the frogbit which was in the old system. The were added and settled in within 30 minutes and fed a little.
This was yesterday evening, this morning all was well. I come home from work at 5:30 pm, most of fish were at the surface and several dead fish on the substrate.
The external filter was from the old community tank and was circulating the whole time, and the fish were only bagged for about 60 minutes.
There was only approximately 15 tetra sized fish and a Bristolnose. When I come home I’ve done a 75% water change and added a second new internal filter which has some carbon inside.
What on earth happened?
