Ulva
is common worldwide in a wide variety of species and locations. It
lives in both temperate and tropical waters seasonally and prefers
water temps of 60-78 degrees. Most are composed of smooth, ruffled
disks attached to rocks, shells or hard bottom by a single
holdfast. Other forms include strips or tubes protruding from the
center of the plant. A
fast grower, its use is nearly as popular in the refugium as
Chaetomorpha. Not only does it efficiently remove excess
nutrients from the aquarium, but it is very palatable to a number
of fish and invertebrates. Ulva is also an excellent macro algae
for culturing both copepods and amphipods in the aquarium.
Although it will attach, typically Ulva is tumbled or allowed to simply
float in a refugium. It can be problematic in a refugium if the
return pump(s) is not protected, as it can clog up plumbing
systems. Palatable to fish.
