See I see what you want to do,but IMO it be best to keep it above the substrate. Just put small 4-5" or so long PVC scattered in there the polys will be pretty much good as long as they can fit in the tubes. Anyways ya try and do something like in the pic I posted stuff like that usually works well for Botha eels and polys
alright, thanks! still tryna figure out how to get a natural look though
