Ecocomplete with some regular sand for dwarf hairgrass?
I was wondering if I could have like a 1 inch bottom layer of ecocomplete with like maybe a 1.5 or 2 inch layer of sand on top of it to grow dwarf hairgrass. I know that the sand will eventually go under, but I'm looking to have the dwarf hairgrass stay in the substrate. Will this be fine or will the sand block off circulation? Also, how deep does dwarf hair grass roots go downward? Thanks~
PS. I already have a layer of ecocomplete (20 lb) on my 20 gall long tank and its maybe 1 inch in height.
