wooz29 Posted June 4, 2006 Share Posted June 4, 2006 Here is a pic of some caulerpa I picked up today. This is my very first macro, any suggestions? http://i7.photobucket.com/albums/y259/wooz29/bf980122.jpg Link to comment
Fishfreak218 Posted June 4, 2006 Share Posted June 4, 2006 the one on the left isnt caulerpa and the one on the right is Halmeda [sp] which needs calcium Link to comment

Fishfreak218 Posted June 4, 2006 Share Posted June 4, 2006 Grape Kelp http://www.liveaquaria.com/product/prod_Di....cfm?pCatId=662 i have it and it doesnt grow anything like Caulerpa.. it isnt invasive or anything.. i could be wrong though.... i never thought much about it... saw that link and just figured it was what LA said it was Link to comment
One Eyed Bunny Posted June 4, 2006 Share Posted June 4, 2006 The left is also commonly refered to as red grape algae. It's similar to most red algaes in that it not photosynthetic and feeds off of excessive nutrients in the water. This type is almost strictly ornamental. Herbivores will eat this at will as it is rather tasty, at least to them. Link to comment

Herbivores will eat this at will as it is rather tasty, at least to them. Ding ding, try again. Red algaes, also called kelps, are all photosynthetic, although they're found in places where green and brown algaes aren't; often in deeper, darker environs, or in surgy, intertidal zones.

One Eyed Bunny Posted June 4, 2006 Share Posted June 4, 2006 You're right. They absorb blue light, and reflect red, making them look red. I'm a newbie for posting this without thinking. ^_^ Link to comment
jeremai Posted June 4, 2006 Share Posted June 4, 2006 No worries. As for an ID, it does look like a red grape kelp, but there's a few different species, so no definitive. It is most likely VERY photosynthetic, meaning the more light the better; other than that, there's no special requirements for it. As FF218 said, though, the Halimeda is calcareous, so you need to keep an eye on your levels - if it's the only thing using calcium for growth in the tank, regular water changes should give it all it needs. Be careful of it going sexual, though. Link to comment

Um, kelp is a brown algae. The closest thing to a true kelp that you can successfully keep would be the sargassum types. I wouldn't worry much about Halimeda going sexual, unless your tank is chock full of it. Link to comment
