I'm currently cycling my first saltwater tank..... I'm using Dr Tim's ammonium chloride and one and only..... My ammonia spiked eventually and now zero.....my nitrites are high in the purple with api test kit .... nitrate is 40 ppm..... Yesterday I put more ammonia in to get a reading and 24 hours later it is zero..... But nitrite is still purple....????? Is cycle done or wait a few days more to see if it goes away I'm doing fishless cycle but can't wait to get fish ..... almost there just wondering what to do or to wait
