Fish Crazy
I had a 240L tank which had been fully cycled and testing fine (0 Ammonia, 0 Nitrite) for a couple of weeks though Nitrates were showing fairly high (80ppm), and had a few fish in plus some plastic plants.
Time came to Plant out the tank with real plants so the following was done:
Removed the fish to a seperate area
Removed 80% of water
Washed Plants in Sink
Planted tank
Replaced Water with Fresh Water and added Fresh Start
Added a couple of heaters to get water up to orginal levels.
Added Back fish
Between Step 2 - 5 the filter was switched off (approx 3-4 hours)
Steps 5-7 was approx 9 hours
12 hours after step 7 noticed a spike in Nitrite to 2.0 ppm, fish have been removed from the tank. It is now nearly 48 hours later and the readings are still showing ammonia 0.5ppm Nitrite 1-2 ppm.
Questions:
Why did this happen our tap water show 0 nitirite?
How do I get the tank bank to a level where it can accept fish? Obviously I currently have other tanks housing fish that should be in this one!
Should I be adding ammonia now the fish are out to help maintain bacteria?
Please note for those reading the Black Neon Tetra thread, it was not in this tank! Just not having a good week!
Appreciate any advice
