Yap, planning to run refugium but I heard that once biopellet kick in the chaeto will lack of nutrient and cannot survive. Now still trying to figure how to make the biopellet more effective.
Yap, already try to skim harder. My PO4 is about 0.15 to 0.2. So far no algae issue yet as I only on my light for 1 to 2 hrs per day. Wanted to reduce the nitrate before introducing coral in.
