Re: [AGA Member] GLosso turning Yellow?



I hope I can make this point without sounding snooty --
watts per gallon is a very rough but readily available
indicator of lighting levels.  It's affected by tank depth,
type of light bulb, ballast factor, useable light per watt
(not the same as lumens), quality of reflector (specular or
painted, parabolic, psuedo parabolic or flat), etc., not to
mention variances bewteen bulbs within the same make and
model.  I think you can safely round off the value to 4
wpg. :-)

Do you know the CO2 levels?  At 4 wpg, in most situations,
you will want to maintain at least 15 ppm CO2, maybe a
little more.
