Bioload for 220 gallon FOWLR and feeding habbits

[ajiisss]

Hello I am trying ot find a balance between my feeding water changes and my bioload. Right now I have a (220 gallon + 55 sump) FOWLR with the following stocks
1) 5 inch emperor angel
2)5 inch golden butterfly
3) 2.5 inch Asfur angel
4) 4 inch swallow tail
5) 4 inch fox face
6) 3 inch flame angel
7) 4 inch purple tang

small fishes
6) 3 lyre tail anthias
7) Royal gramma
8) 1 damsel
9) flame hawk
10) 3 clown fishes

I know the tank is little overstocked even though it doesn't looks like. I am feeding them 2 cubes of food 3 times daily(6 cubes daily). Am I over feeding ?? nitrates normally hovers around 20ppm. The only issue I am facing is PH drop may be due to dissolved organics. water changes are done every 2 weeks 50 gallons . What would be an ideal feeding for this tank.

I have about 1/2 the amount of fish you do in my 600g
I feed about 10 cubes a day. Some cubes are small bits ( rotifers size for coral)
I feed live black and white worms every day.
Once a week they get some chopped clams or a clam on the half shell.
I do run GFO and dose carbon because the extra food needed for my NPS causes a bit of waste

So you have a reef tank?
