Hey everyone, I am posting this for my friend. He recently set up a 26 gallon tank and decided to cycle it with fish....it's been over a month now and he's having problems with high nitrite still.
A few weeks after starting up the tank he put in some of that cycling stuff and we believe it has ruined the cycle..
His reading are: 0 ammonia, nitrite 2.0 (might be a bit higher, difficult to tell but it's in the 2.0-5.0 range :()
nitrate 30mg ph 7.5
only a few fish are present and they were not added all at once.
he had been doing water changes every few days but the nitrite has remained the same.
he's now doing 20-35% water changes every other day...
my question is....are the water changes helping or has the tank started a newcycle/recycling?
I was thinking of giving him some of substrate to add to his aquarium to help speed up the process as my parameters are good.
any advice is appreciated.
