How to grow Macros


New member
Hi is there anywhere I can find out how to grow this algae?

What I mean is, does chaeto need sand bottom? Does caleurpa (sp) need to be attached to rocks? What macros are free floating?

What goes where?

That's a tall order. Best bet is too pick an algae your interested in and do a search on it ;) Though since you mention chaet and caulerpa, I'll give some basics on those two.

Chaet is a free floating algae, as such it needs no sand or rock to attach too. A bare glass tank would do just fine.

Caulerpa on the other hand, needs some attachment point. It can be rock or sand beds.

Common free floating algaes found in the hobby are Cheat, Ulva, Gracilaria and sometimes Agardhiella.
