nope, no sunlight whatsoever, just the Marineland Aquatic Plant 24" @ 8hr / day... and every single one of my plants have new growth all over (moneywort, hairgrass, crypt, amazon swords, java moss, and another that I forgot/don't know the name - has long stems, medium width long leaves and has a spikey-ball looking thing in the middle of the flowers).
thanks for the info on phosphates. I also added a nitrate test kit to my arsenal yesterday (in addition to the standard ph, kh, ammonia, nitrite, and gh freshwater array). it's not necessary to be able to test copper and other traces, is it??
