My tank has habitually been covered in algae and had high nutrients. I added fluconizole about 10 days ago to kill some Bryopsis. Now that the tank has been running with no filter I get results of nitrates 14.7ppm and phosphates 0.10ppm on the Hannah checkers - much lower than it was before I added fluconizole. There is virtually no algae in the display to suck it up… leading me to be confused about these readings.
