I'm using API test strips They test nitrate, nitrite GH, chlorine, KH and ph, should I be using a master kit? I have old seashells and pieces of coral, can I add that to the water, or can you add too much coral?

Thanks for the reply, should I wait until I add the coral, or can I move him when my nitrites are lowered?

Moving my betta out of 20 gallon community tank into 10 gallon tank he will share with 2 snails. Want to get him out of the 20 gallon, because the 8 neon tetras are nipping at his fins. My 10 gallon has been cycling with the 2 snails and gravel I moved from the 20 gallon. My issue is the nitrite is reading at 3 on the 10 gallon, 0 on the twenty. The question, is it better to move him into a tank with elevated nitrite or leave him with the tetras? Also KH at zero, I have crushed coral being delivered this weekend. Both tanks have a good amount of plants with red root floaters.
