I just got my water tested at the local petstore and they informed me my nitrites were too high! They asked how frequently I change my water (20% every other day) and he said that was way too much and was throwing off the chemistry. Instead he said to do the 20% changes once a week. Is this good advice?
I am currently on the 7th day of Seachem's Stability and am probably doing an additional week with these readings. I also use Seachem prime to detoxify the nitrite, and to condition the water/add stress coat, etc.

I will probably also pay a visit to hydroforums for additional knowledge.

Everything is appreciated.
