Hey, new tank here. Finished cycle two weeks ago. Ammonia, Nitrites both 0, Nitrates 10, pH 8.3 ( Red Sea test tough to tell, but in the 8’s) a d Alk is sitting at 5. Testes multiple days, same result. Taking sample to lfs to double check tomm. Used Live sand and cleaned (bleached) rock to start along with Dr Tim’s ( half dose due to live sand). Can’t figure out the low Alk. Anyone? Thanks.
