55 gallon - early stages

So i had decided to upgrade from a 30 gallon biocube to a 55 gallon long. Tank was in the beginning of February and I had to move everything from one tank to the other ASAP. Tank has been doing very well, and I am pleased with everything so far.
Tank specs:
75 lbs LR
40lbs aragonite non-live sand (plus a cup of LS from 29g)
Koralia 1, 3 and 4
Nova Extreme 48'' T5: 3 actinics, 3 10000k daylights
Rena SmartHeater
Fluval 305 canister filter
Flow Rate: 2700 GPH

Parameters:
Ammonia: 0
Nitrite: 0
Nitrate: 10ppm
pH:7.8-8.1
Temperature: 78 C
Calcium: 480

Tank is overly stocked, but is maintained with weekly WC and thorough cleaning.

Tank Stocklist:
1 kole tang
1 blonde naso tang
1 bristletooth tang
1 maroon clownfish
1 banggai cardinal
2 truncate anthias
1 flasher wrasse
1 watchman goby and tiger pistol shrimp
1 cleaner shrimp
*** HUGE bioload i know, but when fish become too large i will remove them --- dont worry

and a few more....

 

looks great

 

gotta love that frogspawn!

 

nice tank but 3 tangs in a 55 gallon isnt the smartest idea they will outgrow it.........good luck though

 

what type of skimmer are you runnning? do you have a fug?

 

I do have a sump/refugium or protein skimmer. I am looking into getting a protein skimmer within the next month, but am so unsure of what i need and what is best. I am jsut browsing and talking at the LFS and seeing if i can get one online. I dont want to buy one that is not good. I am not using a sump/refugium as i have no room in bedroom for it. I am a student living in a student house so i only have my limited size bedroom.
