i've been bitten by the aquaponics bug. This means I need more grow bed area. I want to make what this guy did in his video but it doesn't seem strong enough.

i basically need an elevated trough. I'll frame the trough with plywood and lay a pond liner in it. I just need a safe way to elevate a 4x8' bed about 30" off the ground.
Can I just put six 4x4s in the ground to make the basic shape and screw a ledger board to it then add joists to this? I need vertical support 12" above the bottom support to hold the walls up. Just not convinced strapping headers to the side of a post will be strong enough. If it can be... let me know how
this will be about 32 square feet and have about half a cubic yard of water and a full cubic yard of haydite. I'm estimating total weight of around 2000lbs, or 62 psf. With only a 4' span I was going to use 2x6 16" OC but very nervous about the support of headers.
in the video the guy just used 2x4 for everything but had two for posts.
