Please fill out this form as completely as possible. Use a new form for each aquarium. You can also submit the information on the DFWAPC forum on Aquatic Plant Central and it will be immediately available for everyone.
Aquarium size standard 10 gallon, 20" x 10" x 12" tall
(gallons and dimensions)
Type of light fixture AND reflector OLD hand me down T8 fixture w/ no reflector
(power compact, T5 NO, metal halide, mirror polish reflector, white paint, mylar, etc.)
Number of lamps, bulbs, or tubes, and wattage 1 x 15 Watt 18” T8 Phillips grow light
(examples: “2 T5 HO tubes, 24 w” or “1 metal halide 150 w”)

PAR VALUES MEASURED AT SUBSTRATE: 3 - see comments. Just under the surface of the water I measured 101.
(Tip: you may want to measure PAR in several different locations. You can report multiple measurements, or calculate an average.)
Comments I have a lot of floating plants.
(Are there other conditions affecting light levels? What types of plants do you grow? Was the meter easy to use? Were you surprised by the results?)
