A friend of mine has just introduced his first fish into a newly setup aquarium. He's had them in there for about 5 days now, but the Nitrite levels have spiked bigtime.
It's a deep purple on the indicator... looks about the 0.3 mark, possibly higher... which I know can be lethal to fish.
However, there is 0 ammonia, the test comes out clear... so I'm stupmed as to what's causing it. Shouldn't there be a high ammonia content if there's a high Nitrite content?
Anyway, I've suggested that he do a 30% water change and replace his filter (mechanical filter, has no biological effect... the biofilter is in the ceramic media at the bottom), in case there's something rotting in there.
I added some of my Cycle additive to his tank 3 days ago (double dosage), but it doesn't seem to have helped... if anything, the Nitrite level has risen.
Anyone have any suggestions on how to get the Nitrite level down quickly?
