Maybe just make it 30" high ? I like Franks dimensions for the Instant Ocean units, but just trimming it a bit. Building the sump was interesting, 48" L by 15.5" wide by 18.5" high. All measurements exterior. It sits inside the legs of the 90G or I'd have made it wider. Insides and the edges with about a 4" overlap of the fiberglass. I did two coats, it used just under two quarts. I think its where its going to be for pretty close to forever. The 8' long Instant Ocean unit will cost about $145 in 3/4" Marine Ply and $180 in epoxy. Six pcs of 5/8s glass 12 X 12, and 2 large tubes of silicone. Another ~ $35. I have some pvc 3/4" stock, and a length with ball valves for the plumbing, 6 bulkheads were $ 30. I think that six 28 gal glass tanks would cost more. When its done I'll get some photos of it.

Some good points - I went back and re-read through the IO tanks in Hoff's book. Not worried so much for dermersal spawners (probably spelled that wrong), but for pelagics. I was toying with 2x2x3' tall tanks to see if I could get away with one sheet of glass in the front. Would probably work (and I'd make two so to tie them together with an egg collector) OK and hopefully not be a pain in the behind to move.

Jake and Arc Katana, I am also a big believer in fiberglassed plywood tanks. They can be made in non-standard dimensions, easy to break down and move from your apartment and unbreakable. If all else fails you can cut them apart with a circular saw and use the panels to make a new tank. However I don't think you need the more expensive marine plywood, regular 1/2" may do. Your idea of 36" high tanks is another good one and should work well with demersal spawners. No matter what fish you're working with, you should get more fertilized eggs and better spawning rises out of the 36" height.

Good points, I mentioned a 30" width to get it through a standard door opening. I epoxied my ply tank so I think a good quality ply would do also. And I think on the 8' unit I would prefer two 4' ones just to make them easier to move, if need be. The added cost of two 4' units rather then one 8' would just be for the extra end. The 24" depth of the 90G is about as deep as I want to work in. For a big wall display tank more is nice. But its not going to happen for me. I think the 24" depth will work for smaller pelagic spawners. I am curious how many ply tanks there are out there?

Lots of big freshwater ply tanks - and a few saltwater ones. Monsterfishkeepers.com has lots of builds on there.

Thanks for the link, a great diy site. Much to think about here. I am making a simple swap on my system units, the long box is going to be a refugium and what was the refugium will be the sump. A bigger refugium allows more macroalgae, and hopefully more pods. While there is ample room in the sump for the drip/dry filter, skimmer and return pump. I think I am going to tie in the refugium to the main system, it adds another 50 gals, will do some more nitrite/nitrate reduction, and add some pods to the system in the tank with the mandarin, gobies and similar sized fish.

I'm always a huge fan of more water volume

Me too, those ply monster tanks are sure eye candy. The weight on some would collapse most house floors, still, one for pelagic spawners with a good egg catcher sure makes for lots of day dreams. I'd be very happy with a 2-300 gal one. Maybe when I grow up.
