nitrates

[Montana]

amonia o , nitrates 5ppm , nitrites o , ph 8.0-8.1, calcium 450 , dkh-10, just bought new no2 and ph kit salifert, ca and alk are aquarium pharmacuticals. dont test for mag because i have never had a problem controlling calc or alk. as for phosphates traces.just replaced middle halide 2months ago to 14k from 10k the other 2 are 10 months old 10k. as for cyano remover i am a firm believer in riding the problem instead of masking the problem as you said. it will just come back.
