I don't know what the deal with nitrate and phosphates and dino's is... The last fight i had i think phosphates did get low less than 0.05 and nitrates were low too (less than 5ppm), but the dinos persisted when nutrients were raised.It is a common place in the dynos treatment threads to state that phosphate and nitrate should be detectable, or to say that it is good to increase nitrate and phosphate levels.
My tank has been running for the last year with nitrate levels between 5 and 10 ppm and phosphate levels between 0,06 and 0,2 ppm. Usually nitrate is around 8 ppm and phosphate around 0,1 ppm, what makes a ratio around 80.
For me, i dosed the reef brite rock cleaner bacteria, microbacter 7, live phyto, and just removed that bulsh*** however i could, basting, water changes, filter rolling, etc., getting it exposed to the UV.
