Very Very Nice

Obviously, you are not on your first rodeo with a tank.... Putting your sump in the basement is a Huge WAF!!!!

I assume you are using metal halides for your stoney corals? How much light? Do you use a plenum or just an inch of live sand. Given the amount of coraline algae...(very nice) are you using a calcium reactor? How much help has your algae refugium tank in your sump provided? What kind of flow do you put into your tank from the sump... It looks pretty moderate... thus all the powerheads.... Its a very sterile tank... congrats! Do you have a chiller plumbed into the system as well as emergency power???? it would be a shame to go through a week without power ...

Do you struggle to keep the front glass clean? It is always messy to have to brute force clean the glass with a razor... pisses the wife off with the mess..

Very nice tank!!
