I will grab a pic when i get home but you have most of the basic's. only thing i would reccomend is running some rowaphos (GFO) and running carbon. My set up is very similar and i am in the same boat as for being on a budget. another thing to consider is a ATO like the tunze one. saves you alot of head acks with keeping your water level up to par
