are there any reef clubs in your area. alot of times people will have stuff sitiing around not in use but dont advertise them for sale or only sell to members of their club. and when it comes to diy, some reef club members will even be willing to help you with the build. your situation isnt that unique, meaning lots of people have bow tanks and cant hang from the ceiling, and have had to come up with inventive ways to solve their issue. as for your price point. are you absolutely stuck at 150. i know this hobby is expensive, but you are going to be spending money no matter what. theres no way around that. i not saying you have to go out and break the bank on lights, but it is one area you dont want to skimp on too much. especially if your tank is going to a focal point in your living room. if it was in your man cave down in the basement thats a differnet story. you might not care what it looks like and can slap togther a diy without worry. i have one ( not the only one) light over my tank that looks like something a kid in a grade 7 shop class built. heck they could probably make it better. its a 120w led chip mounted on an ugly heat sink, with a pc fan strapped to it. it looks like hell, but the 20000k light produces is all i care about. it hangs from the ceiling but if i had to id slap together a pvc frame to hang it. i guess my point is, yes you could find a solution for 150, but its probably not going to look very good (over the tank) and the light it produces might not live up to your expectations. and within 6 months youll hate it and want to upgrade. any thing can be done, but what are your expectations. remember its not just i want to keep a few types of coral, that can technically be done with any light, and i mean any (maybe not sps, but shrooms, sponges, etc....)
