for the deeper turtle grass that sounds about right. If you are going that deep though you need a coarse sand bottom (some finer sand will sift down for sure, but a good start) to get some water transfer. I think it will also promote root growth. On my last trip I checked out some seagrass beds and you they had better root development than the beds I have seen. In my area, thick mud runs pretty deep and while the soil provides for good coverage, after about 3 inches it becomes too dense for root penetration. Some of the seagrass banks I saw that were next to carved channels had amazing root growth. Wish I took a picture. Not much into cameras, but the seagrass beds are so healthy in some of these spots I wish I was for a minute.
