any pointers for sphagnum only (with a sand cap) substrate?
I jumped the gun several weeks ago and redid my substrate with 100% sphagnum covered in sand. I have about 3-4" total of substrate evenly divided between sphagnum and a silica sand cap. I didn't really pre-soak any of the moss, I just layered it in and put enough water to fully wet the moss before adding the sand over top.
I realize this isn't very optimal after studiously reading here after the fact and I don't plan on re-doing it with another mix, so is there anything I should look out for or plan for when I start adding plants? I had hoped to add plants sooner, but my wallet just won't let me at this time.
This will be a low light, low tech setup for now. I really like the idea of a ground cover of some sort. Will this substrate be able to grow a ground cover? I'm not sure what I want to use yet as I'm still researching what I can get locally and what I'll be able to afford. I really like the look of micrograss, but really anything that tends to grow short and cover the bottom will work for me.
Would a ground cover respond to root tabs or will I have to rely on a water column fert? I've a serious n00b when it comes to plants, but I am constantly reading EVERYWHERE so direct answers aren't super necessary, maybe just some pointers in the right direction.
This is in a standard 55gal long. Not many fish at this point, but I'm shooting for a community oriented tank that will hopefully support a handful of angels and dwarf cichlids, some schoolers (rumys?) and maybe a shoal of corys to help with cleanup.
