Pulsing Xenia not .. pulsing ?

[OCDP]

Weird... I am going to try and re-position it.. I did a search on RC and lack of nutrients may play a role in the pulsing (not catching any organics in the water) also, high flow will give you lack of pulsing , and apparantley they appreciate a higher light (I thought the opposite) so I'll try and stick it in a higher light/lower flow area and see what happens..
