What should be my next upgrade??

I'm looking to make some upgrades to my setup, Right now I have a fairly well stocked 55G with a 20G fuge I made. All my equipment and my stock list are in the signature below.

I am purchasing my first home in the near future and plan to turn my 55G into a slick fuge and have a large tank, like 120gal+ built into the wall in my basement, so anything added will have to be able to be used on the larger system and hopefully tried out for the time being on the current setup. I don't want to have to re-buy the equipment for the new tank..

Don't have a set budget on the upgrade either so preferably any suggestion made would be awesome if a ballpark price were thrown in just to give me an idea what it would be looking at getting into.

 

if i were you i would look into a controller.. or an mp40 and turn it way down in your 55.. as far as equipment, your prolly gonna have to add another LED fixture

on my 150 im gonna run 3x250 lumatex ballasts, lumatex reflectors, and radium 20Ks.. my skimmer for it is gonna be a 400 gallon reef octopus and a Precision Marine RL 200

im also using a 55 gallon sump..
