i have two 40watt t8's marine whites (each bulb 40 watts)
and two 39 watt t5's marine whites (each bulb 39 watts)
and one 30 watt t8 blue bulb

what wpg do i have in

88 uk gallons
106 usa gallons
 
the two t8s are 40 watt bulbs

forgot about edit
 
dont know if this will help i just copied it from white from tff

Well two 15 wat t8 gives you 30 watts so what ever your tank size is in US Gallons divide that by 30

So for example i have 2x25watt bulbs that gives 50 watts divide that by my tank size 29 us gallons 50/29=1.7 WPG
 
sorry i am not to sure how to work this out for you bae maybe someone else can i just copied it from anothe forum as i remember reading soming about it
 
yeah ive pmed big c
 
using the blue bulb on the us gallon it works out at 1.77wpg, without the blue bulb 1.49 wpg

I presume in marine sense it works out the same as a planted tank would?
 
i geuss it does does any one know what type of corals i can keep under this
 
thats what i was thinking but i wernt sure
 
Are'nt watts of T5 better than watts of T8 though. Don't you get a higher output from them or something like that.


In thoery yes, they penatrate deeper, but as far as im aware they all get counted as equal even though T5 is obviously better. Im sure the WPG rule is worked out on old T12 tubes anyways so full accuracy will never be correct as T8's are stronger/better and T5 are sronger/better than T8.

im sure someone will give a much better explanation soon though lol
 
yeah i pmed big c and he did view the topic but didnt reply so im guessing he didnt know
