Howdy Keith,
Hopefully you'll have a nice FW planted tank or decide to go a large marine planted system, maybe some purple seadragons to go with those seaweeds?
I'm trying to get the Monterey Bay Aquarium to do a nice SeaDragon display with marine macros and seagrasses.
I've pinpointed to them how to grow our local seagrasses well here.
Reefs are also very nice, I am using some smaller seagrasses in an upcoming reef I have planned for the foreground and then a regular coral reef display, just with a nice seagrass front.
Refuges are also an obvious aspect I'm good with.
This is a namely FW plant group, but there are more and more Marine plant folks popping up and trying things.
Regards,
Tom Barr
