I am not to worried about things growing really fast, i mean sure i want to see my corals grow but i dont plan on selling frags unless i have to due to over growth. So i will shoot for the 3x 18Ks and the 1x 460nm actinic I found a good retro kit for the 4 bulbs on craigslist for 90 bucks... i just need to get the bulbs. Also currently my sump is empty its completely euro style right now... im going to drop a glob of chaeto in there a 50/50 should feed it adequately right?

Also going back to my last post... Will I be able to add a clam under the 4x T5s?
