Still having Nitrate problems in the 24 gallon aquapod...

[redtide94]

I have had high nitrates for the past several weeks. The ohter night I did the following.
10% water change
Boiled the sponge material and let it dry
Boiled the Bio balls
Did nothing with the white carbon in the back
Added the black charcoal like stuff in the nylon bag (forgot the name)
Today nitrates still around 40...
50% water change
Took out the bioballs
took out the old white carbon (or whatever it is...it's almost 6months old)
I believe this might be the source of nitrate...thoughts?
I added six little neck clams, 4 died in about 3-4 days and I took them out.
Am I on the right track. Tank is about 6months old.

My tank is almost 2 years old and I still have nitrates around 30. I'm going to follow this thread for insight, sorry I can't help.

I also have a 24 gallon aquapod. My nitrates are right around 25 according to my test kit. I would like to get them down.
I didnt keep any of the charcoal and sponges that came witht the tank in the back for very long. I know the charcoal bags are not the source of nitrates, but I believe that nitrates can hide in there if you know what I mean.
I am too fearful to add anythign to my tank that might get my fish sick (way over paranoid right now, won't even add corals) but you could try some cheato algea if you haven't done that alread. I believe the cheato uses up the nitrates.
