Ammonia and Nitrite

[jrcoolt]

After doing a 50% water change, it doesn't seem to have helped.

My ammonia stayed the same but my Nitrite jumped to .50.

Prior to the water change, they were both reading at .25, hence the reason for the water change. Is prime causing the higher readings?

Also, after the water change, one of my Gold Tetra's has been hanging out by the filter. I did wash the filter media, bit that was in old tank water.

That's odd that a water change would cause nitrites to rise. What are your tap water readings?

 

[jrcoolt]

Tap water reads at zero, that's why I'm stumped.

What size tank? What is the stock? How long after the water change did you test?

Its a 29 gallon, 5 gold tetras and a bn pleco. I tested about 10 min. Also, after doing the water change, I noticed something odd at the roots of one of my plants. Could this be a culprit?
