If you're using it to grow plants, it's too deep. If you want to put fish, (goldfish only, not big enough for koi) the tank is fine as it is, providing you have a shower to aerate the water and get rid of Ammonia, NitrItes and NitrAtes.
If you cut them in half, 2' deep, it is a magnet for coons and birds to get your fish. It is also too shallow for temp stability.
I know many people who use them for small ponds or to raise Tilapia.

Wish I had an entire room dedicated just for more tanks!
