Hey everybody so my water was testing nitrates at 100 on my Salifert test and I got this reading before and after a 20 gallon water change (I have a Red Sea 250 about 54 gallon display ) even after the 20 gallon water change there was no change on nitrates. Could this be accurate? Maybe my nitrates were alot higher than 100.
