Make sure you follow the directions on the phytofeast, overdosing may cause problem algaes. At least that has been my experiance, I seem to get cyno when I use that stuff.
Any macro algae in the fuge?? I would add some macro or caluerpa and a light. The pods
are very cool to watch and you will want a light on the tank. I pod watch all the time. And from the DT's web site they say that phyto is also good for the sand bed critters so yes IMO
add to the main tank once in a while.
