Having troubles

[philjac]

My problem is that I am having a high nitrite reading (off the color chart). The water is a little cloudy (greyish), there is no algea present. I have been doing water changes every couple days (about 15-20%).

I have a thirty gallon tank I started 2 months ago. I am using an out of water filter with an activated carbon airerator. I have started using a product called algone.

I have not been able to shake the cloudyness. Is there anything that I need to be doing differently?? Any help would be appreciated.
