Macroalgae or seagrass for mid-Brackish GSP Tank?

Like the title say, anyone have any success with seagrass or Macroalgae in a mid-level brackish tank? Preferably species that aren't toxic if (when) a puffer takes a bite. Anyone know of a list of specific species that can live in brackish water?

Seagrasses can and do grow in brackish water. But there are various species, and tolerances will vary between them.
Zostera marina for example is known to grow from about 10 to 35 ppt, i.e., about SG 1.006 to 1.025 at 25 C.
On the other hand, growing seagrasses in aquaria can be tricky. Do read, for example, here:

Toxicity shouldn't be an issue, and it's very likely seagrasses are consumed by pufferfish in the wild, whether incidentally or deliberately.

Unless you have some non-trivial experience in operating FW planted tanks at high light intensities (=/>3 WPG), cultivating seagrasses is going to be a major and long-term learning experience. This is an expensive and moderately delicate operation.
My best suggestion would be to try this for yourself first and for a number of months in a tank without fish. Such tank management is not at all that of common hobby fish tanks, even moderately planted and lighted ones.
