Thanks for the id help. I have a power head right above the pagoda. It should be moving quite a bit of water. I may change out for Seio's in the next week or so. Two questions:
1. I dose phytoplankton every couple of days and feed the tank zooplankton and frozen brine shrimp daily. Is that about right for these creatures?
2. On a side note, any thoughts on the light layer of green algae? All the parameters look okay (nitrate, nitrite, alk, ph, and ammonia).
