WTB - Livestock Cold water macroalgae

[tweng]

Does anyone have macroalgae in a cold water (< 60 deg F) tank? I have some sea lettuce (Ulva) from the Cape but I'd like to get more, or other species like chaeto. My understanding is that I can't just use macro algae from warm water but that could be wrong. I'm in Cambridge but can drive to pick up.
