Here is the picture from the Harrietta Hills catalog.
It is 180 gallons. I could not find it on their online catalog. I know that round would be ideal, but 42" x 42" will fit into my space so much better. The round is around 60" in diameter. If anyone knows of a deeper tank that would be roundish and around 200 gallons, please let me know. I can work with under 50" in my space. Rubbermaid has a 150 gallon oval that might work.
I want to raise around 100 tilapia over the winter. I have two fish tanks for the brood stock and raising the small fry. This trough will be for the fish up to about 6 inches.
Coach,
Stay away from rectangular and oval tanks if you can for you first project. Sure you can make them work but it's a lot of extra work and not very cost effective for what you want to do. On the other hand if you must, you can probably get away with it as tilapia can handle dirty water, ammonia, and nitrites better than other species. Maybe it's just me but when I build something I want it as cost efficient and working efficient as possible.
I have a round tank that is 48 inches in diameter that is cut down from a water storage tank. If you can find a plastic tank manufacturer in your area they may have some sitting around they'd be happy to cut down for you. That's what this one did for me:
http://www.assmann-usa.com/Open_Top_Tanks.htmThey told me whatever size I need they will accommodate me if I give them a heads up. Of course it helps I ran cross country and track with the salesman's dad and really talked him up.
The one I got from them, any feces rarely sits on the bottom very long due to the smooth surface, and the spray bar I installed creates a circular flow that sends it down the drain pronto.
I got it for much less than any of the commercial tanks.
Rural King also sells a 4 foot plastic stock tank very reasonably. I can get one from my local store and not pay shipping if I wait for them to get it in.
Whatever you do don't pay shipping for a tank! It can be more than the cost of a tank! It's ridiculous!
