Nothing probably wrong with your lighting, they seem to stay more compact when in brighter light. It is difficult, if feeding fish, to get phosphates as low as harder corals require. Water changes with good ro
water is where you start, but sometimes it takes GFO
or Purigen to knock phosphates down. Also, many test kits get unreliable when testing at the lowest ranges.
