Good evening you all, my tank has been cycling for well over 6 weeks. I'm currently reading 0 ammonia, 5+ppm
of Nitrite, and ridiculously high Nitrate, upwards of 180. I'm just so confused as to what's going on. Everything was working well with spikes, but Nitrite & Nitrate never went back down. It's a 40 gallon breeder, 20 long sump. It was started with a piece of shrimp. It was BRS dry rock & 30lbs of sand. There are no power heads, just a Mag 7 hooked up to a Y loc line for return. Not sure exactly what's going. Using Ro
& have had multiple stores test the water. Each producing the same results! Any help?
