alam ko kasi, you dont add the wattage of the actinics when computing. so watts lang ng 20kK mo plus half ng watts ng 50/50, divided by 50 gallons. i'm sure less than 1w per gallon yan. normally, its not enough (3w per gallon daw eh), but apol has less than 1 watt per gallon din, eh mukhang ok naman.
