Okay, on my 29 gallon, I was using 30 watt full spectrum (two tubes, one 6700K and one 10000K) but it broke. So while I waited for a new one to come in the mail, I used my old 90 watt 6700K. Burned the crap out of my plants (I'll be posting photos in another thread for that one, maybe tomorrow).
SO today I got my new lamps that are 17W 8000K, heavy on the reds, and blues, and I didn't realize that this would mean the things would look purple like moonlight! It looks nice, and subtle, and my husband commented that the fish look happy, but purple? what the heck? The reds in the lights are good, right?
It just seems like my plants aren't going to be able to thrive in such darkness.
