I just got a Taam Rio Mini Sun led lights that clamps to the side of my sump. Check my tank thread for a pic of the lights and my sump with chaeto. I can't tell yet if it's good enough to grow chaeto 'cause I just installed it a few days ago.
i am running a DIY LED string over my sump, but i am not keeping anything like a fuge in there. it just makes it easier to see in there, lol. i know this doesnt help much, but i also have a good friend that is running a string of 200+ christmas LEDs over a nano and keeping montipora and acropora alive and growing !!
thanks for the info,you guys have great tanks.im just looking for a way to keep the heat down and grow some cool stuff in my fuge.with out putting a mh or pcs down their
