lombard0> sir, i used 2 10-watt NOs when I still had gracillaria. plus reflected sunlight. gracillaria also likes turbulent flow nga pala, from my observation, macrolagae likes flow, they tend to grow faster.
I'm still wondering if I had ID'd the algae correctly, Gracillaria and Halymenia looks the same.
halymenia:
here are some pics of the macroalgae:
halimeda renschii:
halimeda discoidea
asparagopsis armata:
asparagopsis taxiformis (cotton candy)
sailor's eyeball (variety of valonia spp.) and valonia
gelidium latifolium
I've seen several species of the above stated macroalgae during our trip in calatagan. except for asparagopsis spp.
(bakasyon na, punta tayo calatagan mga sir! hehe)
apparently, these are invasive and hard to remove. especially valonia.
(sana online si sir horge para may additional info tayo.)
