why are my nitrates doing this

the nitrite reading accounts for 0.00038 mg/L would that interfere

Sorry, I was reading that at 0.38 ppm. At 0.38 ug/L, it is not significant.

so i diluted the hanna checker 50/50 tank and rodi the hanna read 71ppm while diluted but 100% tank water the nyos test reads 65ppm

think i need to just stop the water changes and wait for ICP

i have done about 40x 8 gallon water changes on the tank in the last 3 month the tank is 94 gallons lol
