its from the excess nutritent of all the nitrite and nitrate levels, do your best at lowering them, also nitrite is highly toxic to fish, a level of this means you havent cyled your tank yet

Would the level of jumped so high because of the cleaning, co2 & extra filter I installed last night? I got one new fish in the past week but I don't think that would be enough to kick it off, would it? Is there any way to lower the nitrite quick? I'm scared I'm going to loose everyone.

The algae is in the water. If I turn the light on it almost looks like powder swirling around in the tank. I can only see about 2 inches in.

Thank you all for your help. I really appreciate it

cleaning = loss of bacteria = nitrite spike
CO2 = excess nutrients = algae
New filter, well internal filters are just no good.

 

[musho3210]

just do daily 10-15% water changes to get rid of the nitrite and add some hardy plants to lower the nitrate levels, chemicals wont be needed, and stop using the CO2

what is the medium? A good filter medium is a cartridge of activated carbon and a sponge, any filter can have this, just buy some filter sponge at your lfs, cut it to fit in your filter, then make an insision at the top of the sponge wide and deep enough to fit the cartridge of carbon, then change the carbon monthly but dont change the sponge, just clean it when you are changing the tanks water by gently squeezing it in the bucket of old aquarium water
