So, alot of people have planted tanks these days. I know coco fiber alone doesn't sustain plants, so I added leaf litter, sand, and read somewhere on here that you can ONLY USE ORGANIC FERTILIZER, so that's what I did. I didn't add to much sand or leaf litter ad I wanted my substrate fluffy.

about 1 part sand to 2 parts coco fiber and a couple handfuls of leaf litter.
Question is, if my substrate is wet (but not soggy) do I need aeration in the substrate?

I read that the plants I have love moist soil, but I'm concerned about them not getting enough o2. I read that airstones are a great way. Do I put them directly underneath the plant...?
