Sir Flexi ok lang, we have the same specie. Ours is doing great, we will be having another culture next week. I'll keep you inform. Gave some of my phythos to fellow reefers, no updates from them yet
Phythoplanktons don't need to much light, what they really need is nutrient in order to survive and propagate
HTH
also looking forward for you success
(think positive, wag kang aayaw
)
