"Lagoon" pics

IMO, Caulpera is ok if you really care for it and watch for warning signs of it going sexual. I had kept it in a 33G lagoon style tank for over a year prior to this and never had it go sexual. For my tank, dosing iron seems to be the most important thing. Otherwise the Caulpera starts to fade and get a little "upset".

Other than the 3 types of Caulpera, all I have is Halymenia floresia (red) and Halimeda. Mostly because its hard to find anything different here in vancouver and also because stuff like Sea Grasses cannot compete with Caulpera in a tank like mine. Its just not aggressive enough. Any of the slow growing grasses and algaes die off eventually. J&L has sea grasses sometimes though.

Have you started your 90G as a lagoon yet?

Oh and the Narrow Line was from J&L.
