I have a refugium set-up about a month ago.Water is fed by a small powerhead after phosphate reactor and skimmer. I have cheato and LR and few pieces of Xenia. Lighting is T5 42w on at 5pm off at 9am. I have lots of pods in main tank but hardly any in the refuge. How do I get more pods to grow? Thanks in advance for all replies.BTW the fuge is 40g
