Nitrite/Nitrate Levels

I set my tank up just over 6 weeks ago and used two cocktail sized shrimp to facilitate the cycling...the ammonia has spiked and gone down to 0 however, I can't get the nitrite and nitrate levels to go down. What should I do? I want fish!

Have you cleaned the filters? They are a trap for bad stuff & from what I learned they get dirty fast, I take my 2 filters apart once a week & rinse out all the media & replace what needs replacing, the foam is the major trap use ro water to clean them. After a filter cleaning I can see the diffrenace in the tank
I use a fluval 104 & a 304, will be switching to a sump/fug in the future.

Nothing live in there yet...didn't want to kill anything. I use a Magna canister filter and have two powerheads. I was under the impression that while the tank is cycling, water changes are not recommended.

As far as i know - this point your tank has cycled and this is a normal bi-product. If I am correct - - this point I would do a 20% water cjhange and your levels should stabilize fairley quickley. I would do 10% water changes every 2 weeks or 20% every 4 weeks , levels will spike with the indroduction of fish so introduce fish slowley

Okay, I did the 20% H20 change, changed the carbon in the filter and I still have a .5 Nitrite reading...what next?
