Arowana sump filter w/ refugium set up questions

[Haasume]

This is my plan for a 75 gallon sump filter w/ refugium for my 210 gallon Arowana tank. Do I need to have a seperate line running water directly from the display to the refugium? The intake I have now is 1" and it is a double siphon overflow. I would reduce the pvc to 1/2" for the pipe leading into the refugium. I didn't know if the plants and inverts needed some unfiltered water to thrive. Also if you see anything I should change please let me know. This is my first sump ever so I am have relied on info from the web to make this set up.
I know the pic if horrible but I am computer dumb and I don't know how to use all the fancy equipment to make a nice diagram so I apologize.

separate line as to like be an emergency cut off in case of some sort of power outage? i dont really understand the need for another water line from the display to the wet/dry...make sure the g.p.h. (gallons per hour) of the pump exceed the g.p.h. (gallons per hour) of the water leaving your main display via overflow box or drilled hole...whatever u decide...lmk how it is going!!!

doing this yourself could lead to water quality issues due to chemicals leaching from the epoxy you use to connect the walls of your refugium!!!

how about to just a smaller rubbermaid container with filter media (spongey material/bioballs) inside the larger rubbermaid container?

You can have the interior rubbermaid container lifted on interlocked PVC (poly vinyl chloride) pipes and elbows...

it'll create the filtration you are seeking!!! drilling a hole through the lid of the larger tub for the exit line to go through can help prevent water from splashing onto the floor of your home...the big homie did something really similar to my idea with Brute rash cans like u see on school campuses!!!

your plan looks awesome! it is just the flow of water created by the filtration required to keep your arowana alive might cause disintegration of the parts of your refugium...(epoxy breaking down)

the DIY pic you made looks like it'll look awesome but won't be as sturdy, if aesthetics is your concern, just house the wet/dry underneath the display, hidden by a veneered stand...good luck!!!

FAT Daddy. Thank you for your response. I was planing on using this 75 gal sump because it came with the 210 and the stand along with double overflow box and a few other things. Your idea sounds very good and I will look into implementing it. In the mean time is there anything I can do to make the 75 work? The majority of it is made from 1/4" acrylic and I added some baffles using some 3/4" acrylic I had leftover from making the ridiculously heavy lid needed to keep these suckers from jumping out of the tank.

The extra water line I was talking about would come strait from the Overflow box to the refugium but I don't believe it is necessary. I have 2 1" drain lines coming down to the wet dry/refugium. The return pump I have is rated for 12000L/hr so I think it should be more than enough. If I am wrong please tell me.
The wet/dry filter is not completely DIY it is prefabricated and I just added 3 baffles to complete it. I used GE silicone 1 and a lot of it so it wouldn't come loose. Its currently on day 2 of a 4 day cure before I put any water in it. Once again if you see any problems with this design please don't hesitate to inform me. I don't want 200 gallons of water in my living room anymore than the next guy. Thank you
