A thought just occured to me last night...
A 2-F32T8 ballast (~$7.00 at HD
) should put 64watts into one of these T-5 HO
Im trying to figure out the PAR #'s that would be nesissary for high light needs inhabitants in a 75 gallon tank..
and what the PAR #'s are for one of these T-5 HO
bulbs with the Icecap SLR reflector.
In other words, what would be the maximum number of T-5 HO
bulbs with the above reflectors would be needed over my 75 gallon tank for say clams.
