SRC Member neokn Posted November 8, 2007 SRC Member Share Posted November 8, 2007 That shouldn't happen. Blue or Actinic light are just supplement for the MH. By the way, how many K is your MH? Quote Link to comment Share on other sites More sharing options...

SRC Member reeftask Posted November 10, 2007 SRC Member Share Posted November 10, 2007 It depends how deep is your water and the flow. 10K without extra actinic light is OK as it has some actinic properties Quote Link to comment Share on other sites More sharing options...
