i just setup a tank
dimension : 90 x 60 x 50 cm
i have 2 reefled 90 ..
the tank still cycling, want to put LPS and to create zoa garden
im reading about LPS light requirment , its said low to medium light.
i watch BRS tv said, medium light is 40-50% intensity of LED .. i set my blue channel at 40% with 12 hours photo period, is it enough ?.
what do you think ? i dont have par meter over here.. and no rent par meter.
