Creating your own underwater lawn: Have you thought about setting up a seagrass tank?

There are many themes and visuals to implement when designing and setting up a tank. The coral curation approach is common with a focus on adding many small frags and (hopefully) growing them out into small colonies. This may include an emphasis on blue light to make the color fluorescent corals pop. Other approaches may include a minimalistic layout, a lagoon style, macroalgae, and many other styles of tanks. One approach that would often fall under a biotope design is a seagrass tank that mimic the grass flats of certain shallow coastal area. This approach is unique and can be rewarding, however seagrass tanks can be challenging. Have you ever thought about setting up a seagrass tank?

I have never thought about it before, but I'm sure as heck gonna think about it now!
Its been on my list for a long time but I haven’t done it yet. My plan is to attempt a biotope similar to the Tampa Bay flats.

I actually set up my fuge to be a seagrass tank. On another forum I watched and chatted with an aquarist who very successfully had a seagrass/macroalgae tank. I loved the naturalness of it so tried it myself. Mine did not thrive but I suspect that my lighting was not right. He used a metal halide and supplemented with something else I think. My tank had T5s.

I wouldn't mind giving it another go but right now my mixed reef is looking so good that I plan to enjoy it. I am a one tank gal, well except the sump. Who knows, maybe I will invest in better lighting for the sump/fuge and try again.

I would if I could ever find seagrass.
I have a macro display but no idea where i can buy seagrass.
I've never ordered from the sites below, but they both offer seagrass, and I've heard that they're both legitimate.

For tropical seagrasses (Turtlegrass, Manatee Grass, and Shoal Grass):
For a coldwater seagrass (Eelgrass):

They only have the Turtle grass in stock. Which of the three is easier to grow? I know they are all mostly difficult.

I don’t know - not many people seem to keep them, let alone keep multiple to compare with. That said, the quotes below have some good info that may help:
I don’t think Seagrasses have popped up on their site before. I wish they did :( (though their substrate requirements would probably make it difficult to keep them pest-free).
@AlgaeBarn



Those seem to be the main two sources of seagrass these days. I do not have experience with Aquaticus Plants (@SeaGrass Cullen), though its seems to have a good reputation, and Tropical Fish Plus (@TFP2021) offers manatee grass (Syringodium filiforme) for a great price (20+ individual plants for $8), though the macroalgae I received from them did contain hitchhikers.

Sources that currently have/recently stocked the following seagrasses (in the states):

Turtle grass (Thalassia testudinum):
- Aquaticus Plants
- FloridaPets
- Gulf Specimen Marine Laboratory
- Addictive Reef Keeping

- Gulf Coast Ecosystems once sold turtle grass (Thalassia testudinum)

Manatee grass (Syringodium filiforme):
- Aquaticus Plants
- Aquaculture Nursery Farms
- Addictive Reef Keeping

Shoal grass (Halodule wrightii)
- Aquaticus Plants

Eelgrass (Zostera marina) (coldwater seagrass):
- FloridaPets
- Gulf of Maine

Halophila
- Ask Aquaticus Plants for availability

Outside the U.S.:

Sickle seagrass (Thalassia hemprichii)
- Charm (occasionally)

Pictures?
Some fun seagrass setups for anyone who cares:
Here's a view of the manatee grass (Syringodium filiforme) I am growing in my macroalgae system's DT. It has grown and shrunk over time, but is currently the tallest it has been at over 16" or so:

Other shoots growing in my refugium:

I don’t have any other seagrass, so here are some of the most beautiful, creative, and unique seagrass setups I have seen, in my opinion:
