I have had all the nice looking Macro Algae and ended with bad experiences in the Grape or bell looking one, greatly.
pics from 2016
I have a hard head so didn't get rid of most of it and kept some and just did it over again and have had huge melt downs about 3 times. (only have nano tanks)
Now have Prolifera like yours which I pull out to leave just a few leaves every month probably. It gets mad when changes happen. Like in evap and refilling with a larger amount of RO
in a day, or changes in light and who knows what else causes this to blanch.
Sometimes it is just the tips from maybe too much lighting. There is a tiny bit of Mexican fern which pops up once in awhile I will pull out during the clean ups.
One I DO keep and really, really love so far have had since I got a little bit from a guy at MACNA Late summer 2014 is Black Codium there is also some referred to as Green, Mine has green tint to it too. It is all the way to the top of the Edge tank now. Planning on a nano upgrade so it might grow taller.
I don't seem to have a current pic loaded atm, but here it is when I added a couple chunks to the more recent tank. This was a part near the sand and it got much less light so more green looking.
It stays sort of globe shaped and very mannerly some small parts will break off but it is a kind of slow grower but nice shape and looks so interesting. I do not have a high output light in the tanks (6.6G Edge and 12G rimless)
love it the little fish and crabs will hang out in it and especially the Dwarf Brittle stars like it.
