Have I screwed up my substrate?
OK, I am a rank beginner, but I am at the end of my cycling process on a 55 gallon tank and am about to put the plants in. I am using the full set of ADA substrate.
However, I think I screwed up, I'm just not sure how badly. When putting my hardscape in I ended up moving it around quite a bit, and a fair amount of the mid-granularity substrate is now on the surface. I know that the fine-granularity substrate is supposed to completely cover the surface, especially if you want to grow something like hemianthus, which I do.
How much harder will some of the coarser, mid-level substrate (can't remember the name right now) on the surface make it to grow hc?
And, what are some remedial actions I could take? Would adding in another few cm of the fine substrate be an option? Would that release too much ammonia into a tank that has finally cycled?
