I'm waiting on my tank (32 gallon biocube) to cycle that has live sand, semi-live rock (recycled from a low end brackish tank) and that is being dosed with Seachem Stability. I regularly test my parameters and am getting low readings of ammonia and nitrate, but no nitrite? Is this normal? I thought you should see nitrite before nitrate. I am using RODI water so it shouldn't be the issue. I wanna know my tank is cycled but it seems like its skipping a step...
