How would you filter a 10’x4’x30” ray tank that will be directly on the ground

If I understand correctly... The issue is, he is buying a manufactured aquarium. And beyond 120" the price increases are quite high.

If this were a DIY tank, extending the wooden box would be a nominal cost, probably less than whatever other filtration system is going to add.

The same option is still available with a manufactured aquarium, though it would be costly, less efficient and (imo) a pain in the rear to install. The space on each end is roughly 12"x48"@30" deep, the same as a 110 Gal Aquarium. slide one in each end slot, drill as necessary and plumb them in as filters. Instead of 110 Gal aquariums you could consider some other container of roughly similar dimensions. Since it doesn't need to be see through your options really open up. Some of the suggestions above are in the same ballpark as this.
Yes, this is for a manufactured aquarium, I don’t have the DIY skills to make anything myself unfortunately.

I’ll inquire to see what the extra cost is to lengthen the tank just to see, although I do expect it to be cost prohibitive.

Yes, the cost will go up significantly as acrylic sheets usually come in standard sizes. Wet/dry filters are great for biological filtration. However, there's not room for much mechanical filtration in a wet/dry filter for your 750 gallon tank, and you might find yourself constantly replacing what little filter floss you can get into wet/dry filter. A well designed sump filter would probably be better. However, if you have a drain close by, consider an Ultima II 1000 or 2,000. Ultimas provide both biological and mechanical filtration, and their backwash system make filter maintenance a breeze. You have enough room in your designated filtration area for an Ultima and pump.

This is an interesting idea. I don’t have a drain nearby, but I do have a window. Could a hose be attached to backwash output and ran up the hose and out the window? The landscaping would love that.

Don't know why it wouldn't work. The water will be pumped out. If you go this route, consider a clear connector to monitor the water/debris being purged.

I think I would need 2 Ultima ii 2000 models each with a reeflo snapper pump, do you agree?
Don't know that you need two...but then again....is it possible to have too much filtration? (Yeah, I can say this as I have two Ultima II 4,000s for biological filtration waiting to be set up on my 15'x4'x4' tank upgrade which has been on hold for many years).

IMO, good choice with a Reeflo pump. I've only used one Reeflo pump, but it has run continuously since 2006. The spare replacement pump is still in its box, and I have 5 different Reeflo pumps that have been waiting for years to be installed on the big tank system.

It's important to figure out your filtration before you order your tank. If you decide on sump filtration, you have the option of internal or external overflow boxes which can be done on the side of the tank. I have two 4' external overflow boxes on the back of my tank (to feed and return water to a 405 gallon sump for redundant filtration)

The other thing you might consider doing is having the company place holes in the top of your tank when it is fabricated. Again, you need your filtration figured out before you do this. We drilled four holes on the top of our 300 gallon tank to accommodate the filtration we came up with. On our big tank system, I had the fabricator place eleven holes on the top of the tank to fit bulkheads for 1.5" PVC. Don't want to need a hole saw again.

If you decide to go with Ultimas, the holes would be used for uptakes and returns. If you decide to go with Loc-Line return nozzles, they usually come in 1/2" - 3/4" diameters, so you would need smaller holes to accommodate smaller bulkheads. When it comes to return nozzles, consider a Venturi return nozzle. Venturi nozzles increase the flow rate. The one Venturi return nozzle on our 300 gallon tank spits out a lot of air, so that the tank is well aerated. There has been no need for any other aeration devices. Also they are 1.5" in diameter which matches the rest of our plumbing. I love that the direction of the flow can be changed by simply turning the inside nozzle.

Very good insights thank you so much. The more I read about the ultimas the more I think this is the way to go. The only potential concern I have is how much water would be required for back flushing them?
