I'm at zero nitrates and .64 ppm phosphates. Any recommendations on how to get phosphates down aside from water changes? Anything else I really should test for that is essentially important?
Just a reminder any time you use any phosphate media...lower your phosphates XTRA SLOW over a period of weeks. Otherwise you run the risk of shocking your sps, which will cause them to bleach. Use less than less than the recommended dosage.
