Last saturday i took my full rio 180 stock (except for a baby molly, 9 rummy nose tetra and 2 L333's) to a LFS in trade for a bit of money and 10 rummynose tetra. Everything was fine until Monday morning when i found one dead. I didnt think much too it other than it been a sick fish or becoming stressed in the new tank. The rest of them have all been eating fine and all look fine.
Just ran some tests and heres the results:
Nitrite 0ppm
Nitrate 10ppm
PH 7.2
But get this.... Ammonia .25 - .50 ppm!!!!
Hows this happened? The tanks been running for 6 months plus and ive never had any problems. I did a routine water change (50%) and filter clean (in tank water) on the weekend, after i'd bagged up my old stock ready to take to the LFS. How can i remove the ammonia quickly and safely? I cant take the fish to the downstairs as ive added salt to it ready for some puffers.
Cheers in advance
