what is this

i have no idea what this is. it looks like a red agae pad or something. thanks

 

Coralline algae

 

the dark red pads?

 

ill take a better pic right now

 

so if it is padina, is it good or bad cause i am finding very little on the subject. i found this in a marine botany book. sorry very boring but maybe you can tell me what there saying.

"in addition to the endosymbolic microalgae, which inlcude the zooanthellae,other coral reef algae include phytoplankton, mat-forming and boring microfilamentous algae, and calcified, flesh, and turf macroalgae. the reef flat and crest sometimes appear almost devoid of macroalgae,yet the surface may consist of crutose corallines. in contrst, the unconsolidated sediment in reef lagoons conaints psammophytic green (e.g.,caulerpa) and red algae (e.g., amphiroa, galazura),plus seagrass beds that support and abundant epiphytical flora. fleshy algae (e.g., codium, padina, halymenia) are also common in lagoons, but they may be limited to crevices in coral rubble or under coral heads of patch reefs. the cover of macroalgae and seagrass can range from 10 - 100% in lagoons, depending on the intensity of grazing, nutient, as well as submarine illumination and water movement."

 

i always thought that was some type of encrusting coraline algae.
but who know's, never heard of padima. i don't think it would be bad unless it is overtaking space needed by coral.

 

I think it looks cool as hell....I would pay for that!!!! (If it is safe) Looks like a form of Coraline

 

Yep....it's a crustose non-geniculate coralline algae. It's just a more rare species.

 

maybe a could send you a piece of lr rubble covered in it with the protein skimmer;D
