Stock tanks - any good for keeping rays?

[digitalcomatose]

Hi Guys,
Looking to get a couple of stock tanks to keep some rays in. Curious is any one has used a feed stock tank before?
Is there any problem with the following three products? I'm not interested in comments about size, but more about if there is problem with the material for putting chemicals in the water or durability.

Option 1

Option 2

Option 3

Any other concerns I should be looking out for?

Thanks in advance

I've seen people use all three but if you use the galvanized one I would put a pond liner in it. I've heard they can leach metal into the water.

I really like my pentair tank which has a glass window.

The 300gal. Rubbermaids work good. I am currently running one, used to have rays in it. No problems. Harder to keep a close eye on them than a tank w a window though.

Where did you get the pentair tank? Cowturtle? I think I saw someone make one of those tanks look like a beautiful furniture aquarium. They placed wood around it that covered the whole tank except for the viewing glass...so it basically hid the container since he had it in his living room. Looked amazing, was awhile back. Just curious how cost effective the tank is compared to glass/acrylic

Here's where I got it at the time shipping was free but it might not be worth it with the cost of shipping.

I remember that post with the trim too it looked great.

Those Pentairs look great and as posted, some nice varnished or treated wood surrounding with just the window on show would look great and you could even insulate between the wood and tank. I would want a good lid but you could hinge that off the wood or have cover glass in runners.
