alright, here's the situation, ive been searching the net trying to get the correct lighting for my 20 gallon tall for sps
all i have come accross is wattage per gallon which does not mean squat, it think its a very stupid way of measuring light. the appropriate amount of light, i can have a tank thats a 5 inch square but but high enough to hold 20 gallons of water, if the light doesnt reach the bottom then the light is no good, i know this is an extreme exaduration but geeze, all i want to know is how far does light wattage per lumin penetrate water for pc
lighting and what lumenus is required to penitrate roughly 8 inches of water for sps
is there a chart that i missed somewhere? the perfict chart would be a chart that had differnt lights, MH
, showing the lumins per watt, Kelvin rating differences and HOW DEEP kelvin, and lumins penetrate water !!!!!!!
there must be a professor out there who has spent time making this chart, please tell me that this chart is out there somewhere.
you see, i tried to compare my tank to larger tanks, you have 55 gallon long tanks, then you have small tall tanks, now WPG
seems to only refer to if you place corals all along the base of the tank and not just right smack in the center, i understand that larger tanks have light which utilize longer bulbs ( VHO
) and that MH
only cover a particular area, i just want to know how many watts are needed to penetrate X amount of depth with PC
lighting using acatinics only.
i currently have a 65 watt 50/50 pc
over a 20gallon tall, im interested in adding just an acatinic pc
