Filter for my tank

[canucksfan1]

I know i have a DIY wet/dry made from a 88 gallon rubbermaid, so the out put on that will be one side, i am gunna put the fx5 on the other side, so do u think that would be enough filtration????
I want to move my 3 clown loaches to that tank, and add a couple more.
I also want:
Arawanas
Clown Knifes
Oscars
Possibly the commone pleco from my 55
And some rays if compatible???
Any suggestions for numbers???

k well i scrapped the plan for rays, and have finished my overflow, wet/dry (minus the pump) and the re-sealing, now i just have to wait to test fill it and see if my silicone job holds
