Hi guys Ive been using a API master set which expires in 2024 Im not convinced my nitrate kit is working. Yeah I know they need alot of shaking Ive even been using my paint vortext mixer / shaker so they are more than shaken well. Everytime I test my tank it says its 5.0 ppm which it has done since i flooded the tank (this is the 4th week). I also tested my tap water (i use ro) that also tested at 5. So today I thought id try a tottaly different test kit a tetra one
