I would say that's a fairly average Bioload, in comparison to my nitrate factory you will do just fine. I'm running a 170g, 65g, 70g, 30g and 30g all plumbed together (so close to 350g) and the following all live in there:
1 Purple Tang
1 Yellow Tang
1 Orange Socket Tang
1 2 Spot Bristle Tooth Tang
1 Yellow Mimic Tang
1 Chocolate Mimic Tang
2 Square Back Anthias
1 Mcoskers Fairy Wrasse
1 Long Fin Fairy Wrasse
1 Yellow and Purple Canary Wrasse
2 False Perc Clownfish
1 Coral Beauty Dwarf Angelfish
2 Adult Bangii Cardinals
9 Toonie sized Baby Bangii's
1 Saddle Back Clownfish
1 Copperband Butterfly fish
1 Tail Spot Blenny
1 Bi Color Blenny
1 Lawnmower Blenny
1 Bi Color Dotty Back
6 Peppermint Shrimp
2 Cleaner Shrimp
2 Blood Shrimp
1 Blue Harlequin Shrimp
... 4 Times they are fed automatically during the day, 1 VERY large feeding right before the lights go off.
