High Nitrites

Question
I've had my aquarium for two months now and about two weeks ago my nitrite levels began to rise.  Currently it's at 2ppm.  Unfortunately I did not know about cycling my tank prior to adding fish and i feel this is the reason for the problems since i have no bacteria to control the nitrites, but shouldn't i be growing the needed bacteria after 2 months now? I am doing a 30% water change daily which I started two weeks ago when i noticed the nitrites were on the rise.  I even tried to eliminate any possibility of the tap water contributing to nitrite levels by only doing the water changes over the last two weeks with pure spring water (which i tested and is very soft with no impurities).  I have 5 green neon tetra, 5 glolite tetra and 3 ghost shrimp to clean the bottom.  I have a 10 gallon tank with an air stone which is always on, and an over-sized marineland penguin filter with a bio-wheel.  Any advise? I'm really worried about my fish and shrimp, thank you so much!

Hello!!!
Try the Tetra Easy Balance or some ammonia free chemicals becuase nitrite is also like ammonia, the toxicity of nitrite is related to pH.
Also try some stress-free chemicals so your fish/crustaceans won't feel all stressed out and tired. You can buy them @ your local petshop such as Petsmart and Petco.
Also, try changing the airstone or clean/rinse it if your airstone is washable.
Hope that this helps!
